While with responses to keyboard

Hi all,

I'm a rather inexperienced python programmer. I'm looking for some construct that will start an indefinite loop (eg. while True or something similar) and the program will respond to the keyboard events. Something rather simple: q - get out of the loop and quit, 1 - do something, 2 - do something.

Code:

def some_function:
    pass

def other_function:
    pass


my loop:
    if key == "1":
        some_function
    else if key == "2":
        other_function

Thanking you all.

etc.

I think it is called event driven programming. I can't find anything relevant. It's all about Twisted which looks like has a lot of opponents. Could you recommend something? I don't need/want GUI and I'd like something different than "input" where you need to press enter after the user input.

curses
http://docs.python.org/3/library/curses.html should help. You'll want raw or cbreak mode.

Remember the command
stty sane
or you could use the atexit module to register a cleanup function that restores normal terminal functionality.

One more question. I'm trying to get the centre of a window so that I can position, eg. a title right in the middle regardless of the size of my terminal window.

Thank you

Code:

>>> import curses
>>> w = curses.initscr()
>>> w.getbegyx()
(0, 0)
>>> w.getmaxyx()
(24, 80)
>>> w.addstr(12,38,'hi!')
>>> w.refresh()
