How to stop the program when the output fills the screen in python?

How can I get the status of the terminal from a Python program? I want the program to stop printing lines to the screen when the screen is full and wait for user input.

If you need more control over the terminal window, and assuming you're on Linux/*BSD/MacOSX, then you will need to use curses for that. This is just a simple example:

import curses
stdscr = curses.initscr()
stdscr.getmaxyx() #returns the width and height of the terminal screen
stdscr.getyx()    #returns the current x,y position.

You should check the library reference for more functions.

The simplest (no code) way to accomplish that is to pipe your program's output through a pager program like less or more (assuming *nix), like:

infinity.py

import random

while 1:
   print random.randint(0, 0xffffffff)

command line

python infinty.py | less

...gives output like:

848605718
899092472
2576425641
3098821373
259379057
164782822

2682214542

:

...and waits for user input.
