Dependency Management in Python
summary
Compares classic setuptools + requirements + virtualenv workflow (simple files, manual pins, no lockfile) with newer tools that add a lockfile, automatic envs and publishing; notes Poetry produces a lockfile, package hashes by default and can publish builds, describes pip-style limitations where installs don’t reproduce exact transitive versions, and shows an upgrade command that selectively updates packages. Demonstrates gaps (manual scripts still needed for some production workflows) and when each tool actually works.
