Ah thanks, that was my issue. I was doing an '''import re''' for testing and left it in the solution instead of the tests part. My bad.

@hufftheweevil am I missing something here?

:/ I didn't know that python even had prototyping, and I'm pretty sure my solution doesn't include it.

I just finished the problem and was exited to submit, but now it fails one of the anti cheating checks and says "You're asking for trouble...". What does that actually mean, I dont think I'm doing anything illegal in my solution.
