I just got into Python and have been using tkinter to design GUIs which has been fun so far. I've been experimenting with the frames, and I was trying to separate the screen into 3 'panes' if you will. For some reason, even though the combined widths are less than the total width, it still extends past the bounds of the screen.
For the life of me I can't figure out why the purple frame is cut off on the right.
I am somewhat suspicious of the amount of times I've used padx and pady. Also am curious if it's related to grid_propagate or pack_propagate, which is why I have used it so many times.
Any help is appreciated.
