[Tutor] Python GUI

[Luke Paireepinart]

The error message tells you everything... On line 60, you try to add to "number" but the variable hasn't been defined.

We aren't going to debug your code for you, do YOU think it will work apart from this? Have you tried running any of the code? It's almost always better to build small parts and test along the way than to write out a whole program and try it at the end.
