OK I've got 2 really big classes > 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done.

To make things clear here's what it currently looks like:

from gui_events import GUIEvents # event handlers
from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI

# GUI.py
class GUI(gtk.Window, GUIEvents, GUIHelpers):
    # general stuff here stuff here

One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.
