SEFrame | Effective Framework for Session-based Social Recommendation | Recommender System library

I do not see an entry widget for an input line so I will just work with the stuff inside of ioFrame.

I am assuming yo want the label with the SUNKEN relief setting to stretch across the frame its in.

The way to accomplish this is to add a weight of 1 to the frames column the widget is in first by doing:

ioFrame.columnconfigure(0, weight = 1)

Then you need to change:

I'm going to assume here that you came to python from another language because of all the semicolons. In python, YOU DO NOT NEED SEMICOLONS. I understand at the top if you really want to keep those variables all on one line, but each line in your script should not end in a semicolon.

Secondly, if you print out the value of any button you you have put in a variable, you will see that it is None instead of a tkinter.Button object. This is because of that .grid(...) call at the end of the line (grid returns None). Typically, I only put widgets into a variable if I intend on using it later in the app. If not, I do what you did with the labels, just called them without some_variable_name = in front of it. If you ever try to do anything with those button variables later, it will not work because they are all None.

As mentioned in the comments, I was unable to get your provided code to run because you are using .grid(...) and .pack(...) to place the Frames on the window. You only need one. That was actually what caused the errors for me. Think of the window or Frame as a container; if you use grid to put something in that container, then you cannot use pack to put something else in the container. The different methods of placing widgets conflict with each other. I believe the output you got was because it would place the Frames using grid, then re-place them using pack which is why they are vertically aligned.

So taking all of this into consideration, this is what I have:
