I have to wonder how well that analysis code works in practice. for a lot of intro-level (and some mid-level) course assignments, there's only one or two straightforward ways to write the code. sometimes these assignments are just pasting together sample code from the powerpoint with a couple tweaks. I was a TA for a few of these courses, and the correct solutions tended to be very similar. I was only sure students were cheating when they made several of the same mistakes.

re the 1:1s with TA/professor, I agree. if you can explain code that you didn't even write, you might be even more deserving of that A.
