Is there something simple I'm missing? import winsound try: for freq in range(100,32000,100): winsound.Beep(freq, 1000) except KeyboardInterrupt: passThe KeyboardInterrupt ​exception is raised when someone presses Ctrl-C. If you catch it, and ignore it (which is what your code above is doing), then pressing Ctrl-C doesn't do anything. If you just take out the try/except, then you can hit Ctrl-C and interrupt your program as normal.
What do you mean "doesn't do anything" ? It certainly terminates the loop, which was the intent. Provided of course that something else isn't trapping the Ctrl-C first.
