There is something wrong (with I think my function??) that is stopping this from working. I don't know what part is going wrong
It is saying that its getting a 'TypeError: get() missing 1 required positional argument: 'self' '
Also, if someone could explain 'frame.rowconfigure' and 'frame.columnconfigure' a little more to me because I don't really understand what it does.
Any guidance with this would be greatly appreciated :)

I am trying to create a program that a user will input a number they want to convert from fahrenheit to celsius and press go, and it will calculate it.
