I have a timer, and need to know if any of the keys is pressed on any cycle. How do I do it?
If you are using Windows, Use PyHook If you like to know system wide key press events.
import pythoncom, pyHook
def OnKeyboardEvent(event):
print Ascii: , event.Ascii, chr(event.Ascii)
print Key: , event.Key
print KeyID: , event.KeyID
print ScanCode: , event.ScanCode
print Extended: , event.Extended
return True #for pass through key events, False to eat Keys
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
pythoncom.PumpMessages()
If you are using Linux it s found in the curses module, if you use Windows it s in the msvcrt module.
