The "works on my machine" sentence almost always traces back to a missing environment boundary, and one venv per project plus pyproject.toml is what turns the fix into something the next person can reproduce. The import \* warning deserves its own line: losing track of where a name came from costs real debugging time.

Absolutely! Reproducibility starts with making the environment explicit, not just documenting how to set it up. A project-specific venv and `pyproject.toml` reduce environment drift, while avoiding `import *` keeps dependencies clear and debugging much easier. Small practices that save a lot of time as projects grow.
