EDIT: a question: when I have to use Python, I like to break up my code into small libraries and make wheel files for my own use. How do you handle your own libraries? Do you have one special local directory that you build wheel files to and then reference that library in your requirements.txt files?
We didn't build wheels. We had a centralized git host (Gitlab, but any of them works) with all our libraries, and just added the git url (git+https://...) to the requirements.txt
