This is a pure python (or as close as possible) keyboard hook module.

Thank you this is just what I needed. To make this work on 64 bit windows, I had to add

windll.user32.SetWindowsHookExA.argtypes = (c_int, wintypes.HANDLE, wintypes.HMODULE, wintypes.DWORD)

at line 39, and I had to change line 51 to print(e) to make it work with python 3. Other than that, flawless.

How would you do this if it were Mouse Click Events?
