This is only tangentially related to improving your code directly as you have asked. However, in a similar vein as using source control (git), when using Python learn to manage your environments. Venv, poetry, conda/mamba, etc are tools to look into.
I used to work with mostly scientists, and a good number of them knew some Python, but none of them knew how to properly manage their environments and it was a huge problem. They would often come to me and say "I ran this script a week ago and it worked, I tried it today without making any changes and it's throwing this error now that I don't understand." Every time it was because they accidentally changed their dependencies, using their global python install. It also made it a nightmare to try to revive old code for them, since there was almost no way to know what version of various libraries were used.
This is huge. Unfortunately, as you indicated, there's no standard tool for this and new ones are being added to the mix. Many in the science feilds are pushed towards Conda but I'm not sure it's the best option. However, Conda will be infinitely better than not using anything to manage environments and dependencies.
