[Tutor] tkinter in Python 3

[Michael Thomas]

I'm trying to move a Python 2.x program to Python 3.x. When I try to import
tkinter I get the error message that no module _tkinter can be found. I've
tried sudo apt-get install python-tk. While this command works, there is no
difference in the result. This problem has only cropped up after I changed
to Ubuntu 15.04. Does anyone have any suggestions?
Thanks in advance for any help.
