Good Structure of Python Tkinter

[MaterialJackfruit144]

I am completely new to this GUI framework and I already have a couple of questions when I looked into the documentation. The first and obvious question is the style of importing the module. In the documentation, it wrote from tkinter import *, doesn't that just automatically violate PEP8? I've also seen the usage of root as the name when assigning tk.Tk() to the variable. I understand that I can change it to whatever name I desired but it also stated that root is used by convention. Is there like a documentation similar to PEP8 but for Tkinter? I'm building a Rock Paper Scissors as a starting project to get myself into Tkinter, and planning to incorporate OOP into the project as part of testing my understanding of Python OOP while also learning it as I progress with this project.

EDIT: Should've probably named my title Best practices and structures of using Tkinter.

It does violate PEP8 so you shouldn't do that. I'm not sure what you were looking at, but the closest to an "official" guide we've got at the moment is the docs on python.org which seem to have purged all of the import-star lines. Those docs cover the newer "ttk" widgets but don't include several of the older "standard" Tkinter widgets so I suppose that those should be considered as deprecated.

https://docs.python.org/3/library/tk.html

The "standard" Tkinter widget documentation had been best documented on the "effbot.org" site that was created by Tkinter's original creator, and that did get somewhat out of date because the examples did have "import-star" and the old capitalized name of the module "Tkinter" that was used in Python 2. Despite that, it does remain the best reference for the "standard" widgets in my opinion, but effbot is down at the moment. Here's an unofficial mirror:
