If you assign to a name, Python makes it local, unless you explicitly tell it that you want it to be global: def update(): global GLOBAL GLOBAL += 1 But be aware that the ALL_CAPS name conventionally means a constant. Since you're changing its value, it's not constant (wow! :) ), so using a name of GLOBAL is a bad idea. (Also, obviously, you want to name it appropriately to what you're doing, but I assume you called it this as part of cutting down your example. For which, by the way, thank you. You posted a complete example, and the full traceback, and the Python version and platform. That's everything that we need to help you - it's such a luxury!!)
