General principle: When you see a syntax error, look *before* that
point (reading top-to-bottom, left-to-right, same as the parser does).
Often, the problem is prior to the point where it was actually
discovered.

Specific point: It looks like perhaps you're trying to assign in the
middle of a function call. That doesn't do what you think it does, but
on sufficiently-recent versions of Python, you can do this with
"input_var := tk.IntVar". That might be the easiest solution.
