That still doesn't explain why you only have a print() statement print
Python statements, rather than execute these Python statements.

Why, exactly?

Then do it, I'd suggest.

That's basically any file that contains, or is supposed to contain,
non-printable characters, or where \n has another meaning than
liebreaking. You normally read a plaintext file line by line and a
binary file byte by byte.

OTOH, *if* your claim that you understand the concepts mentioned by Dave
isn't an ill-minded overestimation, I wonder why you don't go and use
these skills. Doyou lack a concept of how to logically build up your
code, or what's the main issue?

That's good ☺!

The thing the python interpreter calls, that is not in a class:, def: or
some other block.

You're welcome back with your results ☺!
