ImportError: No module named Tkinter when importing swampy.TurtleWorld

Question

I am using Python 3.4 and following along the book "Think Python: how to think like a computer scientist". I actually figured out this issue a week ago, but saved over the original code when it failed to run like it did last week. Right now I have:

import tkinter
from swampy.TurtleWorld import *

which yields:

ImportError: No module named 'Tkinter'

When I had the code working last week, I loosely recall that in the 'import tkinter' line, there was a portion at the end that looked like this: [Tkinter]. I tried import tkinter as Tkinter but it doesn't work.

If I change it to Python2.7. And run

import Tkinter
from swampy.TurtleWorld import *
world = TurtleWorld()
bob = Turtle()
print (bob)
fd(bob, 100)
lt(bob)
fd(bob, 100)
wait_for_user()

The TurtleWorld window opens but there is no turtle. How can I get this to work again (Python 3.4 preferred)?

Your file name. What is it? If it is named `tkinter.py`, then change it — OneCricketeer, Dec 04 '16 at 23:17
Immediate lesson to learn: use version control for everything. Second lesson: Python is case sensitive, it's Tkinter in 2.x but tkinter in 3.x. — jonrsharpe, Dec 04 '16 at 23:29
running `from Tkinter import *` `from swampy.TurtleWorld import *` returns ImportError: No module named 'Tkinter' — assutu, Dec 04 '16 at 23:41

You're trying to run Python 2 code in Python 3 that loads Python 2 specific modules (Tkinter) and it's not going to work.

The default TurtleWorld package is Python 2, but there is an unsupported Python 3 version from the Green Tea Press' Swampy: Installation Instructions page. Go to the Python 3 section at the bottom. You will either need to install this package manually or just keep it in your working directory and import it from there. (The instructions explain this.)

Another alternative is to use the turtle module that comes with Python 3, as it's functionally similar for most turtle-related experiments. (I've answered TurtleWorld questions on SO using the Python turtle module.) For example:

from turtle import Turtle, Screen

bob = Turtle(shape="turtle")
print(bob)
bob.fd(100)
bob.lt(90)
bob.fd(100)

screen = Screen()
screen.exitonclick()
