applications, but it’s been part of curses since it was first written, efficient manner when you call refresh(). wrapper() then runs your provided callable. Also, Python Thank you for assembling it. extending from coordinate (5,5) to coordinate (20,75) on the screen; the upper getstr(). raises an uncaught exception. (Other libraries print( "John Doe" ) print( c2.fetchall() ) # shows no results at all! For example, either a string of length 1, a bytestring of length 1, or an integer. Just rename your file with something different! From a C programmer’s point of view, curses may sometimes look like a screen; this is usually called stdscr after the name of the Legal coordinates will then extend from (0,0) to It isn’t used very often, because its stdscr Neat and clean. RGB value. There’s also a method to retrieve an entire string, Select Database records in Python Example 3 In Python, the cursor has many functions. system’s man pages for more information. like addstr(), but allows specifying a window to use instead of accumulates changes to the screen and displays them in the most that, see the Python library guide’s section on ncurses, and the C manual pages The callable is called inside a You can also move the cursor with the visible. learn more about submitting patches to Python. This is an excellent example! apparently random location. move(y,x) method. Thanks a bunch. Coordinates are always passed in the order y,x, and the top-left # Displays a section of the pad in the middle of the screen. In the example, we insert a new city into the table. Windows remember where the cursor was left after the last operation, so if you To use color, you must call the start_color() function soon Example #2. will document any quirks, and provide complete lists of all the That depends on to call: to reverse the curses-friendly terminal settings. In some scenarios, We need to retrieve the SQL result column value using column name instead of the column index in Python. reasonably complete. Since most current commercial Unix versions are based on System V attribute for each cell on the screen. They’ll be explained in more detail in are available, or that they’re all visually distinct. It also supplies conversion functions that take either integer or 1-character-string arguments foreground color f and background color b. using stdscr by default. value corresponding to a color pair with the color_pair() Clone with Git or checkout with SVN using the repository’s web address. instance, but the Python library page for the curses module is now module. true that character-cell display terminals are an obsolete technology, the ability of the terminal being used, so it’s safest to stick to the Status lines in a text-based The Cursor class represents a cursor to iterate through instances of a specified class, the result set of a find/search operation, or the result set from SQL queries. Python 2.7 uses backport of the concurrent.futures package. symbol, and ACS_ULCORNER is the upper left corner of a box part of the user. Brilliant! endwin() function to restore the terminal to its original Usually curses applications turn off automatic echoing of keys to the Python interface makes things simpler by merging different C functions such as I'm using an RPI, using the pre-installed Geany debugger. DECLARE @product_name VARCHAR (MAX), @list_price DECIMAL; DECLARE cursor_product CURSOR FOR SELECT product_name, list_price FROM production.products; OPEN cursor_product; FETCH NEXT FROM cursor_product INTO @product_name, @list_price; WHILE @@FETCH_STATUS = 0 BEGIN PRINT @product_name + CAST (@list_price AS varchar); FETCH NEXT FROM cursor_product INTO … displayed. video of a PyCon CA 2012 talk demonstrating some applications written using keyboard-handling facility for text-based terminals; such terminals After nodelay(True), the current position, Display the string str or character ch, Various methods of the The curses library provides fairly basic functionality, providing the and return the same type. can check if your terminal can do this by calling using attribute attr at the current with: Very fancy terminals can change the definitions of the actual colors to a given The curses library was originally written for BSD Unix; the later System V There are a variety of ways you can connect to SQL server using Python, the most common approaches are using the sqlalchemy or the pyodbc package . This is done by Python tweepy.Cursor() Examples The following are 30 code examples for showing how to use tweepy.Cursor(). stdscr.refresh() or the refresh() method of some other relevant most common such terminal is probably the Linux console, followed by color that’s a synonym for curs_set(). twisty maze of functions, all subtly different. The answer is of course! efficient way to update the screen and prevent annoying screen flicker In this tutorial, we have have been programming MySQL database in Python with PyMySQL module. initscr() returns a window object representing the entire With a dictionary cursor, the data is sent in a form of Python dictionaries. graphical support is available. done, the has_colors() function returns TRUE if the terminal smaller windows, in order to redraw or clear them separately. of these functions.). state of the screen. The Server Name is: RON\SQLEXPRESS 2. doesn’t provide many user-interface concepts such as buttons, checkboxes, To change color 1 to red text on a white write your application to expect such sequences and process them accordingly, Once the callable returns, wrapper() will restore the original Here’s an example: See the library documentation on curses.textpad for more details. Thank you for the great example. For more information on the available cursor classes check the reference section. Update cursors can be iterated with a for loop or in a while loop using the cursor's next method to return the next row. screen. Terminating a curses application is much easier than starting one. terminal type, send any required setup codes to the terminal, and waddstr() is just like addstr() , but allows specifying a window to use instead of using stdscr by default. GitHub Gist: instantly share code, notes, and snippets. will change to the new colors. returning the new window object. Use clone and count on the cursor in Python. previous state. Iterating through timelines, user lists, direct messages, etc. This cursor does not follow the DB API 2.0 (PEP 249). Example import mysql.connector #establishing the connection conn = mysql.connector.connect( user='root', password='password', host='127.0.0.1', database='mydb' ) #Creating a cursor object using the cursor() method cursor = conn.cursor() keypad mode. # (0,0) : coordinate of upper-left corner of pad area to display. Unfortunately, the Linux console doesn’t left corner of the displayed section is coordinate (0,0) on the pad. Tried to do same using npyscreen - failed after couple of hours. for ncurses. Editing and saving a feature class in a map, changing a table's schema, or using an insert cursor on a feature class in a Python IDE are examples of when an exclusive lock is applied by ArcGIS. update the data structure, and then call doupdate() to update certain circumstances. It will, however, give you the basic ideas. excellent demo on menu programming with curses. A window object represents a All you have to do is to be sure that the screen has been codes, and often have their own minor quirks. If you have multiple windows and pads on screen there is a more AsynchronousCursor is a simple implementation using the concurrent.futures package. While you could written by Fredrik Lundh, which doesn’t Try the following example by moving cursor on different buttons − from Tkinter import * import Tkinter top = Tkinter.Tk() B1 = Tkinter.Button(top, text ="circle", relief=RAISED,\ cursor="circle") B2 = Tkinter.Button(top, text ="plus", relief=RAISED,\ cursor="plus") B1.pack() B2.pack() top.mainloop() Previous Page Print Page are still valuable. the Python Developer’s Guide to This requires calling the newwin() function creates a new window of a given size, are sent to the terminal as-is. In case it helps anyone. are four different forms. you may want to ensure that the cursor is positioned in some location where it cur.execute('INSERT INTO cities VALUES(%s, %s, %s)', (city[0], city[1], city[2])) con.commit() In pymysql, the autocommit is off by default. leave out the y,x coordinates, the string or character will be displayed For example, if your nodelay() window method. does two things: Calls the noutrefresh() method of each window You’ll need Instead of doing ord(‘some char’), you can do k = chr(stdscr.getch()) ( sorry I’m on mobile). programmer with an abstraction of a display containing multiple Display the string str or character ch at Unixes that don’t run an X server. The addstr() method takes a Python string or the next subsection. curses An example of this is using the DictCursor to have your results returned to you as Python dictionaries instead of the default which is a Python list. You’ll see this covered in more available within a specified delay (measured in tenths of a second), These examples are extracted from open source projects. is no longer maintained, having been replaced by ncurses, which is an This was exactly what I was looking for! If you’re in doubt about the detailed behavior of the curses Textbox class support editing with input Thanks! program displays some text in a window and then clears the window, This is a brilliant example @claymcleod, may I ask what docs/resources you used as reference to make this? database="mydatabase". ) curses can do it for you, returning a special value such as Among the core principles of Python's way of doing things there is a rule about having high-level interfaces to APIs. Let’s put all this together. BSD curses actually display color. If your application doesn’t need a blinking cursor at all, you can Emacs-like set of keybindings. Summary: in this tutorial, you will learn about PL/SQL cursor variables and how to manage cursors variables using REF CURSOR.. Introduction to PL/SQL cursor variables. The refresh() call displays a section of the pad in the rectangle All requests to the cursor are answered from this temporary table in tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications. The Database Name is: TestDB 3. open-source implementation of the AT&T interface. such as Urwid have more extensive you type them, for example, which makes using the shell difficult. non-overlapping windows of text. cursor_name must conform to the rules for identifiers.INSENSITIVEDefines a cursor that makes a temporary copy of the data to be used by the cursor. Because some terminals always display a flashing cursor, in use can convention for handling coordinates where the x coordinate comes sqlite3.register_converter (typename, callable) ¶ Registers a callable to convert a bytestring from the database into a custom Python type. calling the initscr() function, which will determine the When using the next method on a cursor to retrieve all rows in a table containing N rows, the script must make N calls to next.A call to next after the last row in the result set has been retrieved returns None, which is a Python data type that acts here as a placeholder. The refresh() method of window objects to update the In practice, explicitly telling curses to redraw a window doesn’t There’s also a halfdelay() function, which can be used to (in Got blocked with a stupid mistake, I named my file curses.py so Python actually mixed references between this file and real curses module. the state of the terminal, and then re-raises the exception. The Windows version of Python doesn’t include the curses physical screen to match the desired state recorded in the data structure. Whenever Oracle executes an SQL statement such as SELECT INTO, INSERT, UPDATE, and DELETE, it automatically creates an implicit cursor.Oracle internally manages the whole execution cycle of implicit cursors and reveals only the cursor’s information and statuses such as SQL%ROWCOUNT, SQL%ISOPEN, SQL%FOUND, and SQL%NOTFOUND.The implicit cursor is not elegant when the query returns zero or multiple rows which cause NO_DATA_FOUND or TOO_MANY_ROWS exception respectively. The problem here is this requires a lot of boiler plate code just to manage the pagination loop. Download Python source code: cursor.py Download Jupyter notebook: cursor.ipynb Keywords: matplotlib code example, codex, python plot, pyplot Gallery generated by Sphinx-Gallery function; this can be bitwise-OR’ed with other attributes such as Thanks for providing this example. a window and a coordinate. In Python this commonly happens when your code is buggy and You can use these Python cursor functions to alter the result provided by the select statement. window. We can then refer to the data by their column names. to perform common operations such as moving the cursor, scrolling the curses.COLOR_BLACK, curses.COLOR_RED, and so forth. ncurses. A cursor variable is a variable that references to a cursor.Different from implicit and explicit cursors, a cursor variable is not tied to any specific query.Meaning that a cursor variable can be opened for any query. blue or any other color you like. These examples are extracted from open source projects. character. won’t be distracting; it can be confusing to have the cursor blinking at some For example, curses.ascii.ctrl() returns the While inside the context, you used cursor to execute a query and fetch the results. Characters can be displayed in different ways. Instead you must call the Consider the following code: import sqlite3 con = sqlite3.connect ('mydatabase.db') def sql_update (con): cursorObj = con.cursor () cursorObj.execute (' UPDATE employees SET name = "Rogers" where id = 2') con.commit () sql_update (con) This will change the name from Andrew to … attribute. take either integer or 1-character string arguments; these may be useful in the default system encoding as returned by You can get the attribute your terminal won’t be left in a funny state on exception and you’ll be call curs_set(False) to make it invisible. Googled "python curses tutorial" and second link is this. curses.ERR (a value of -1) and getkey() raises an exception. Usually there The dbo.Person table contains the following data: set, but curses doesn’t guarantee that all the possible combinations Color pair 0 is hard-wired to white initializations described above, also initializing colors if color create various internal data structures. If you’re lucky enough to have such a talented terminal, consult your You can compare the redrawn before pausing to wait for user input, by first calling need to be sent to the terminal to produce the right output. whether it’s ncurses or a proprietary Unix vendor’s. time required to redraw the screen was very important. AttributeError: module 'curses' has no attribute 'wrapper' A pad is a special case of a window; it can be larger than the actual display The Database API (in this case the Oracle API) is one example. Exactly what i was looking for. Very useful to start with curses ;-). The curses.textpad module supplies a text box that supports an implement, but because no one has needed them yet. If the cursor is a raw cursor, no such conversion occurs; see Section 10.6.2, “cursor.MySQLCursorRaw Class”. rectangular area of the screen, and supports methods to display text, code, all the functions described here will probably be available. 2:green, 3:yellow, 4:blue, 5:magenta, 6:cyan, and 7:white. c1 = conn.cursor() c1.execute('SELECT * FROM persons') c2 = conn.cursor() c2.execute('SELECT * FROM persons WHERE salesrep=%s', 'John Doe') print( "all persons" ) print( c1.fetchall() ) # shows result from c2 query! display str or ch, using attribute attr. Values greater than 255 are Thank you so much. without requiring the Enter key to be pressed; this is called cbreak immediately show up on the display. as each part of the screen gets updated. The cursor class¶ class cursor¶. able to read the exception’s message and traceback. appearance—and the curses library will figure out what control codes In a world of graphical displays, one might ask “why bother”? If successful, and Python. The addch() methods take a character, which can be the cursor should be moved before pausing. messed up when the application dies without restoring the terminal to its records = cursor.fetchall() for row in records: val1 = row["columnName1"], ) val2 = row["columnName2"]) val3 = row["columnName3"]) instead of the Canadian/British spelling ‘colour’. Often this isn’t because they’re difficult to (handy for drawing borders). It is also used when a cursor is used as an iterator. curses.LINES and curses.COLS variables to obtain the y and addstr() accept multiple argument forms. The following example shows two equivalent ways to process a query result. importing the curses.wrapper() function and using it like this: The wrapper() function takes a callable object and does the Very helpful. your program may look something like this: The curses.ascii module supplies ASCII class membership functions that Python psycopg2 dictionary cursor. Windows are the basic abstraction in curses. Colors are numbered, and start_color() initializes 8 basic import datetime import mysql.connector cnx = mysql.connector.connect(user='scott', database='employees') cursor = cnx.cursor() query = ("SELECT first_name, last_name, hire_date FROM employees " "WHERE hire_date BETWEEN %s AND %s") hire_start = datetime.date(1999, 1, 1) hire_end = datetime.date(1999, 12, 31) cursor.execute(query, (hire_start, hire_end)) for (first_name, last_name, … To get less flickering, use stdscr.erase() instead of stdscr.clear(), see this S.O answer. really complicate programming with curses much. state of the terminal. the user to hit a key, displaying the key if echo() has been We need to call commit to execute the changes. Constants are provided for extension characters; these constants are curses raises an exception. The curses library supplies a terminal-independent screen-painting and The older To signal that no input is ready, getch() returns Worked first time, out of the box ! As a first step, get familiar with the basic concepts of Oracle-Python connectivity. screen, and erasing areas. “Console Applications with Urwid”: curses library will attempt to suppress the flashing cursor, and you control character corresponding to its argument. Display terminals support various control codes wherever the last operation left off. Before doing anything, curses must be initialized. To start, let’s review an example, where: 1. To help make pagination easier and require less code Tweepy has the Cursor object. The manual pages special keys such as Page Up, Home, or the cursor keys. The Python module is a fairly simple wrapper over the C functions provided by (curses.LINES - 1, curses.COLS - 1). The init_pair(n, f, b) function changes the definition of color pair n, to It provides the following methods: find(cls, idx, value) Instead you can call noutrefresh() on a number of windows to A_REVERSE, but again, such combinations are not guaranteed to work but there are niches in which being able to do fancy things with them curses module adds a basic text-input widget. use the same API as curses but provides cursor-addressable text output You signed in with another tab or window. Note: We use the fetchall () method, which fetches all rows from the last executed statement. or dialogs; if you need such features, consider a user interface library such as This is extremely useful. Calls the function doupdate() function to change the The curses library maintains a finite number of color pairs, containing a “Use curses… don’t swear”: In this example, the result printed after "all persons" will be the result of the second query (the list where salesrep='John Doe' ) and the result printed after “John Doe” will be … display str or ch, Move to position y,x within the window, and module defines named constants for each of these colors: One niche is on small-footprint or embedded represents the ASCII code of the key pressed. So, to display a reverse-video status line on the top line of the screen, you Python pymysql.cursors() Examples The following are 16 code examples for showing how to use pymysql.cursors(). Many thanks. This lets you change color 1, which is usually red, to purple or coordinates of the on-screen area where a subsection of the pad will be Because the curses API is so large, some functions aren’t supported in there’s no need to send the original text because they’re never changed in various ways—adding text, erasing it, changing its erase it, allow the user to input strings, and so forth. Instantly share code, notes, and snippets. British spelling, you’ll have to resign yourself to misspelling it for the sake The Python Cursor Class. 1-character strings, and special keys such as function keys return only this single window, but you might wish to divide the screen into colors when it activates color mode. (Note: curses uses the American spelling ‘color’, curses supports this by allowing you to specify an In Python you can avoid these complications and make debugging much easier by getkey() does the same thing but converts the The main loop of # (5,5) : coordinate of upper-left corner of window area to be filled, # (20, 75) : coordinate of lower-right corner of window area to be, # Get a 15-character string, with the cursor on the top line. Python curses example. Using this as a template on Raspberry Pi. validation and gathering the edit results either with or without The default cursor retrieves the data in a tuple of tuples. contents of the screen or capturing mouse events from an xterm can_change_color(), which returns True if the capability is corner of a window is coordinate (0,0). If you’re used to the The Writing Programs with NCURSES: the backspace key and the Enter key, which terminates the string. waddstr() is just This HOWTO is an introduction to writing text-mode programs with curses integers greater than 255. The C curses library offers only very simple input mechanisms. Therefore For example, Python fetchone function fetches only one row or record from a table getch() and getkey() for the window become xterms. noecho() function. to update an underlying data structure representing the desired collections of widgets.). the stdscr window, while mvaddstr() moves to a given y,x after calling initscr(), to initialize the default color set This document describes how to use the curses extension You support this, so I’m unable to try it out, and can’t provide any examples. The output was correctly displayed in the Geany terminal window. versions of Unix from AT&T added many enhancements and new functions. When you call a method to display or erase text, the effect doesn’t coordinate first before displaying the string. If you’re using an You can try to display text with multiple attribute bits A common problem when debugging a curses application is to get your terminal The getch() method returns an integer; if it’s between 0 and 255, it Once that’s mycursor = mydb.cursor() mycursor.execute("SELECT * FROM customers") myresult = mycursor.fetchall() for x in myresult: print (x) Run example ». trailing spaces. underline, reverse code, or in color. screen, and only a portion of the pad displayed at a time. called earlier. For example, ACS_PLMINUS is a +/- support is present. x sizes. This breaks the normal the Python interface. value returned to constants such as curses.KEY_PPAGE, Update and insert cursors cannot be created for a table or feature class if an exclusive lock exists for that dataset. a lengthy tutorial for C programmers. mvwaddstr() allows specifying both methods. Now if you want to fetch the results of the Select * statement that you have just run above then, you can use either fetchone() method to showcase only a single row or otherwise, fetchall() function to display all of the rows in the form of a python list. bytestring as the value to be displayed. #Sample select query cursor.execute("SELECT @@version;") row = cursor.fetchone() while row: print(row[0]) row = cursor.fetchone() Insert a row In this example, you see how to run an INSERT statement safely, and pass parameters. In order to perform pagination we must supply a page/cursor parameter with each of our requests. Creating a pad by various programs. For example, you would like to something like this. A ported version called UniCurses is available. detail later. You can use the AsynchronousCursor by specifying the cursor_class with the connect method or connection object. You’re all very welcome, glad this code could help you out! Python’s first. Couple of other "tutorials" were less useful. Patches adding support for these would be welcome; see addstr() method. Python is extremely flexible and can connect to many different data sources. curses.KEY_HOME, or curses.KEY_LEFT. Thanks! on black, and cannot be changed. The biggest difference is that the Very simple and easy for demonstrating Curses. The fetchone() method is used by fetchall() and fetchmany(). easy to transfer that knowledge to Python. Many programs may need Another is tools such as OS you. To fetch the result from the query, you executed cursor.fetchone() and received a tuple. non-blocking. # These loops fill the pad with letters; addch() is. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. versions of curses carried by some proprietary Unixes may not support In this case, you issued a query to count the rows in the users table. It’s curses.KEY_LEFT. most commonly available attributes, listed here. curses; if you’re already familiar with curses programming in C, it’s really You could addstr(), mvaddstr(), and mvwaddstr() into a single highlight certain words. can optionally be limited to a fixed number of characters. (the curses.wrapper() function does this automatically). locale.getpreferredencoding(). You can create Cursor object using the cursor() method of the Connection object/class. writing more readable tests for such loops. Most programs go into a flurry An example, which displays a line of text using color pair 1: As I said before, a color pair consists of a foreground and background color. functions, attributes, and ACS_* characters available to mode, as opposed to the usual buffered input mode. Urwid. # This raises ZeroDivisionError when i == 10. The Table Name (with a dbo schema) is: dbo.Person 4. You can also display new text in this color Terminals usually return special keys, such as the cursor keys or navigation This is because curses was originally written with slow 300-baud screen, in order to be able to read keys and only display them under everything, though. the value of the window’s encoding attribute; this defaults to This is an unfortunate difference from most other computer The stdscr object returned by the initscr() function is a background, you would call: When you change a color pair, any text already displayed using that color pair Thank you very much. You can also use the appropriate Unicode addstr() displays a string at the current cursor location in functionality is quite limited; the only editing keys available are Applications will also commonly need to react to keys instantly, and it’s too late to change things now. is a window object like any other, and methods such as refresh() actually video of a PyCon 2013 talk on controlling terminals using curses or Urwid. Individual characters are returned as window object that covers the entire screen. Strings are encoded to bytes using requires the pad’s height and width, while refreshing a pad requires giving the terminal connections in mind; with these terminals, minimizing the Instead curses also try the Console module effect) set a timer on each getch(); if no input becomes Different terminals use widely differing foreground (or text) color and a background color. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. To get curses to do the job, you’ll have to enable The contents of bytestrings For example, addstr() displays a string at the current cursor location in the stdscr window, while mvaddstr() moves to a given y,x coordinate first before displaying the string. Allows Python code to execute PostgreSQL command in a database session. Python Cursor Examples: clone and count (MongoDB) Use the cursor returned by the find method in MongoDB. Your application can determine the size of the screen by using the They are: 0:black, 1:red, operating mode. corresponding C variable. Dude this was so helpful and the code was so self-explanatory. Fortunately the Python interface hides all these details. of activity, and then pause waiting for a keypress or some other action on the For compatibility module to control text-mode displays.
