3 RisposteHey there,
I don't know why, but when I import tkinter on IDLE like this:
from tkinter import *
And I say:
window = Tk()
Even known I use python 3.2.5, which should be able to use Tkinter, the python shell raises a ValueError that says that Tk() is not defined. I am very sure I use python 3.2.5 and tutorials from the Python Foundation say that is what I have to do. But it still doesn't work.
Does anyone have an idea of how to solve this problem? Thank you!
