No, it doesn't. It specifically avoids the problem of environment pollution by letting you just make another environment. And it avoids the problem of interfering with the system by not getting added to sys.path by default, and not being in a place that system packages care about. PEP 668 was specifically created in cooperation between the Python team and Linux distro maintainers so that people would use the venvs instead of "globally pip installing packages".
> requires a bit of path mangling to work right, or special python configs, etc. In the past, it's also had a bad habit of leaking dependencies, though that was in some weird setups.
Genuinely no idea what you're talking about and I've been specifically studying this stuff for years.
> It's one of the reasons I would recommend against python for much of anything that needs to be "deployed" vs throw away scripts. UV seems to handle all of this much better.
If you're using uv, you're using Python.
