I'm trying to create a simple gui program in python however when I try to run it I get this error:

This is all I have in code.

from Tkinter import *


test = Tk()

test.title("Reverse")
test.geometry("300 x 200")

test.mainloop()

   'import site' failed; use -v for traceback
        Traceback (most recent call last):

  • in 2.7 you mmay want to try `from tkinter import *` I cant remember but at some point it is lowercase .... annoying i know but maybe thats the issue? what happens if you just do `import os`? – Joran Beasley Jun 26 '14 at 19:23
  • @Joran Beasley in Python2 it is uppercase, in Python3 it is lowercase. – furas Jun 26 '14 at 19:38
  • btw: better don't use space in file name `Reverse a String.py` (and in folder name too) – furas Jun 26 '14 at 19:43

test.geometry("300 x 200") should be: 
test.geometry("300x200")

Also, make sure you are correct in how you installed tkinter. On a linux machine, use: 

sudo apt-get install python-tk

  • After changing test.geometry I'm still getting the same error. Also I'm on windows which I believe the python install includes tkinter with everything else. – Hotshot55 Jun 26 '14 at 22:56
  • Did you incorporate the changes furas referred to? The test.geometry was another issue with your code. – user3681650 Jun 27 '14 at 02:17
  • Open the python interpreter and just type "from Tkinter import *", what is the error that is shown? – user3681650 Jun 29 '14 at 23:41
