After you have explored the vastness of the tkinter realm, I'd suggest you explore other GUI libraries: wxPython (https://www.wxpython.org/), PyQt (https://riverbankcomputing.com/software/pyqt/intro), and PyGTK (https://pygobject.readthedocs.io/en/latest/). You may find out one of these works better for you, or it makes it easier for you to code the application you need.

I believe that coders can realize their ideas only when they are conscious of what tools they have available. If your toolset is too narrow, your ideas may seem impossible or extremely hard to realize, and they risk remaining exactly what they are, just ideas.

Of course, the technological spectrum today is humongous, so knowing everything is not possible; therefore, when you are about to learn a new technology or a new subject, my suggestion is to grow your knowledge by exploring breadth first.

Investigate several things, and then go deep with the one or the few that looked most promising. This way you'll be able to be productive with at least one tool, and when the tool no longer fits your needs, you'll know where to dig deeper, thanks to your previous exploration.
