I'm getting a Tkinter error even though it was imported and used yesterday. I have a Windows 7 OS and am running Python 2, so I'm not sure what I'm supposed to do at this point. My google-fu is weak today, I can't seem to bring up anything relevant. Any input would be greatly appreciated.
This happens when you most likely have more than one Python installed on your system and you're running the program from a version different from the one you programmed it in. 
By default, a Python program on your PC will usually be opened in the latest edition of Python.
"ImportError: No module named Tkinter" even though I've used Tkinter programs as recent as yesterday and no substantial changes were made?
