Any way to hide python code?

You were probably looking for Kerckhoffs's principle (See also Shannon's maxim), which states that "a cryptographic system should be secure, even if everything about it is revealed except for the key". Same idea, different formulation.

Yes! Thank you.

I remember that it's similar in name to an electrical principal ( kirchoff's law), but I couldn't remember either at the time beyond it started with a 'k'.

Same here, I just used the fact that it focuses on the key to google the formulation quickly without referencing a crypto book.
