Importing tkinter and others to Python node

Hi everyone,
I’m starting my way to understand how Python and the frameworks around it, and I have a newbie question.
Since Dynamo supports Python 3, is it possible to import libraries such as tkinter and make forms with the Python node in Dynamo ? if not, which libraries are we limited to use in the Python Node ?
Thank you

Problem resolved in here : Tkinter can be used in dynamo - #4 by chuongpqvn
