Pypi.org is running a survey on the state of Python packaging

I'm not sure what you mean - unlike npm, pip installs only one copy of a dependency in each environment.

So if I have environments A, B, and C and each has a dependency ML-package-1.2 that's 100 MB, it means there's one copy of it in each environment? Meaning 3x100 MB?

By default, yes. It is possible to install ML-package-1.2 into your 'base' python and then have virtual environments A,B and C all use that instead of installing their own copies. However this is generally not considered best practice.

Ah, so across multiple environments? You do have a point, but that has nothing to do with pip - it's not an environment manager.

I can see that as an option in tools like venv or poetry, possibly setting a "common" location to share across environments.
