I would love to hear positive python packaging stories because my other language packaging experiences (lisps, R, rust) felt so much better. Did you try to maintain python packages on a system with old gcc that cannot be upgraded and walk through the dependency hell explicitly while having SAT solvers fail to find compatible solutions after minutes at a time? Have you managed to keep bit-level reproducibility on future reproduction runs for more than five years in any other way than keeping the old OS and hardware around? What are your packaging tools of choice (setup.py is obsolete soon, poetry did not stick, pyproject.toml for the win I guess, conda at glacial speeds, pip too slow and prone to security risks, uv faster but incomplete, …)? Did you not encounter packages with dependency specs that no longer worked on future dates?
