getch is a callable object (it implements __call__()) and is used like a function. If you only want to run on Windows, as your code suggests, just call msvcrt.getch() directly. This is a blocking call - it won't return until a key is pressed. If you don't want to block, use msvcrt.kbhit() to check whether a key is available before calling getch(). > break > print c > ================================================ > > No more errors, but it doesn't do what I wanted.
