Try new things. Simple over everything is the key to production python code. Too many layers of abstraction is a massive footgun, especially if youre passing objects around a lot, due to dynamic typing etc.

Constantly circle back and refactor. Ruthlessly.

Same as in any lang, focus on data structures and algorithms (business logic is algorithmic) rather than the implementation, at least to start with. Get it working (usually easy in python, it's so dynamic!), make it good, make it fast. A good data model makes coding a joy. If your data structures suck every little thing will accrue friction. This is a red flag that you chose the wrong data model.
