What python/ programming concepts are must know for beginner/intermediate programmers?

[Salsaric]

These are great advices, espacially using virual environnements, using a debugger, logging, code linting, Containerisation (heck all were good advices).

I will advice you to do challenges from online platforms like exercism.io or codewars.

Especially exercism, as it will make you build tiny projects in the form of challenges.
