python - Difference between tkinter and Tkinter

Question

When I answer Tkinter questions I usually try and run the code myself, but sometimes I get this error:

Traceback (most recent call last):
  File "C:Python27pygame2.py", line 1, in <module>
    from tkinter import *
ImportError: No module named tkinter

When I look at the question I see they import tkinter with a lower-case t:

from tkinter import *

I always import Tkinter with a capital T:

from Tkinter import *

Which always works for me. What is the difference between using tkinter and Tkinter?

Answer 1

It's simple.

For python2 it is:

from Tkinter import *

For python3 it is:

from tkinter import *

Here's the way how can you forget about this confusion once and for all:

try:
    from Tkinter import *
except ImportError:
    from tkinter import *
