Python - get key pressing ?

[Krisztian Kepes]

Hi !

I want to create an py program what process datas for long time.
But: I want to abort it if I need.
Not with Ctrl+Break !

If I push a key (B, or other), the script must stop his work, and save the result created before.

What I need to catch the keyboard events - without stopping a script ?

Example:

while False:
DoWorkPeriodic( )
if KeyEvent=='B':
SaveWork
Stopit

Why not? Ctrl+Break, or more typically Ctrl-C, is the de facto standard
approach for terminating a console (non-GUI) application.

In this case, just wrap the code with a "try/except KeyboardInterru pt" and
put your "stop and save" code in the except block. (Note that Ctrl-Break
will bypass this, but Ctrl-C is caught as you would expect.)

Also, when posting questions of this nature it's a good idea explicitly
to specify your platform (Linux, Windows, etc).
