I vividly remember the frustration when trying to make some very simple application imports working. There's a couple of gotchas, the biggest one being that you need to write imports based on where you expect to run your applications from. Perhaps obvious for experienced python devs, very much surprising for newcomers. And then I was quite shocked by the state of package managers in python. You need to learn pip, venv (with references to "virtualenv"), these are too low level, so you find pipenv, which is unbelievably slow (installing a single dependency can take 10 minutes), so you need to learn to use it with "--skip-lock", but then you lose locking ... I've never appreciated node's bundled "npm" so much before which mostly "just works".
