Why import duplicates from a module

Question

I am learning tkinter and noticed that people import multiple things sometimes.

from tkinter import *
from tkinter import ttk

I was wondering why people do this for many modules, not just tkinter. I always thought that import * meant that you were importing everything from a module. So why do people import more items?

Why people do things they should not, is an eternal and unanswerable question. — Stephen Rauch, Mar 29 '18 at 03:24
Importing **everything** is a bad sign. Says that "*importer*" doesn't know what they're doing (in most of the cases). — CristiFati, Mar 29 '18 at 03:29

tkinter.ttk is a submodule of tkinter. Submodules aren't guaranteed to be loaded by import *; if you want them, it's safest to import them yourself. (Whether submodules are loaded by import * depends on the presence and contents of an __all__ list, as well as what imports __init__.py performs and what imports have already been performed.)
