New status: I´ve refactored the code trying to follow the recommendations from the guys who answered this question. The new version is on the link above.

Edit: New version at Python 3 Tkinter Calculator - follow-up

I´m a beginner developer and I chose Python as my initial language to learn. This is my very first project: a calculator using tkinter for GUI.

I´ve tried to apply some OOP and modules approach, as an attempt to make it like a real job, instead of simply put it all on a single file or procedural mode.

I need some feedback about module naming and organization, class naming and organization, pep-8 style, structure in general.

I tried to use separate modules and classes as an attempt of using good practices.
