TKinter in Python - advanced notions

[Andreas Heckel]

Hi,

Apologies for potentially mis-using this thread. But I have been struggling recently making exactly this leap from simple GUI examples to a more elaborate MVVM concept. Mainly I have been struggling finding nice example python code bases, that allow some understanding to the beginner, which I certainly still am, but also show enough complexity to see the concept in action.
Any hints / links to github or similar highly welcome. If the list is not the appropriate place, I am happy if you email me directly.

Cheers,
Andreas
