How can I import Tkinter in Python.Script?

I am trying to do this:

from tkinter import *

but I recieve this message:

Message: No module named tkinter

Traceback:
line 2, in , “C:\Users\jvarona\AppData\Local\Temp\TempScript.py”

Can anyone help me?

Thank you.

I think Tkinter is Python only, not IronPython but I might be wrong
