Some python programs display a graphical user interface. Others run in a text-mode console (dos prompt, unix shell, etc). And yet others don't have any display at all. If you're talking about a graphical user interface app (windows, dialogs, buttons, etc), then you'll have to rely on the particular user interface library you are using to provide that sort of access. If you're just running in a dos box, or a unix terminal, then there are other ways of doing what you want, but I'm not sure any one way is portable across all operating systems. I did find this code segment that claims to work on windows and unix: http://code.activestate.com/recipes/134892/ Anyway tell us more about what environment and kind of program you are dealing with. As for callbacks, of course. functions are objects in python. You can pass them as arguments, assign them to variables, and then call them. All graphical user interface libraries rely on them to handle events. -- https://mail.python.org/mailman/listinfo/python-list
