Why can’t I access tkinter objects after importing tkinter as something?

I’m following a simple tutorial, learning about the tkinter library. In the tutorial, they do this:

 from tkinter import *
 from tkinter import ttk

I was told the above is not good practice so instead I did:

import tkinter as tk

However, later on in the code I have to do something like this:

mainframe = ttk.Frame(root, padding="3 3 12 12")

This gives me an error because I didn’t import ttk as its own module. I would assume something like this should work:

mainframe = tk.ttk.Frame(root, padding="3 3 12 12")

yet it also gives me an error. How do I access the ttk module if tk.ttk.Frame is not the way to do it?

Answer

ttk is not a part of the tkinter module, it is a different file in the tkinter.

In order to import ttk you have to do this

import tkinter.ttk as tkk
