Python Tkinter Call A Dictionary With A Stringvar?

I'm working with tkinter in python and I have an annoying bug that I can't seem to fix, although the answer is probably obvious. I am trying to call a dictionary with a string, bu

Solution 1:

Just as you had to call set method of StringVar object, you also need to call get to retrieve the str data.

print weightsy[acadw.get()]

The dictionary doesn't know to convert your object into a string so it attempts to get the value associated with acadw. You get a TypeError rather than a KeyError since StringVar objects happen to be unhashable.
