Created October 13, 2015 17:32
Listening to KeyPress and KeyRelease with Tkinter with debouncing
import Tkinter as tkinter
tk = tkinter.Tk()
has_prev_key_release = None
'''
When holding a key down, multiple key press and key release events are fired in
succession. Debouncing is implemented in order to squash these repeated events
and know when the "real" KeyRelease and KeyPress events happen.

Python global and user config variables + git. The idea behind this is that you have one central place to keep config variables with the option of having user-specific variables outside of user control. Useful for working with API keys and other sensitive data. Simply put user-specific variables in config_user.py.
