If you're using this entirely on your own code, one good way to solve
the problem is to make your code always importable. Protect your
top-level code with "if __name__=='__main__':" (and possibly put it
into a function main() if that simplifies your code counting), and you
should then be able to import it as-is, and all you'll do is define a
bunch of functions/classes.

But counting lines of code is a hairy thing to do. Do blank lines,
comments, and multi-line strings count?
