Managing Dependencies in Python with Poetry
summary
Demo shows Poetry replaces the virtualenv + pyenv + pip dance: it creates per‑project venvs, writes pyproject.toml and a lockfile, poetry add/remove/export resolves versions and removes transitive deps that are no longer needed, and reproduces installs with the lockfile. A sample project runs on Python 3.9 while the host is 3.11, a packaged wheel is built and successfully published to PyPI, and dependency trees are inspected with poetry show instead of manual pip freeze. poetry publish to PyPI works.
