Why I Still Use Python Virtual Environments in Docker (via) Hynek Schlawack argues for using virtual environments even when running Python applications in a Docker container. This argument was most convincing to me:
I'm responsible for dozens of services, so I appreciate the consistency of knowing that everything I'm deploying is in
/app, and if it's a Python application, I know it's a virtual environment, and if I run/app/bin/python, I get the virtual environment's Python with my application ready to be imported and run.
Also:
It’s good to use the same tools and primitives in development and in production.
Also worth a look: Hynek's guide to Production-ready Docker Containers with uv, an actively maintained guide that aims to reflect ongoing changes made to uv itself.

How I’m a Productive Programmer With a Memory of a Fruit Fly (via) Hynek Schlawack describes the value he gets from searchable offline developer documentation, and advocates for the Documentation Sets format which bundles docs, metadata and a SQLite search index. Hynek’s doc2dash command can convert documentation generated by tools like Sphinx into a docset that’s compatible with several offline documentation browser applications.

Hynek Schlawack: Testing & Packaging (via) “How to ensure that your tests run code that you think they are running, and how to measure your coverage over multiple tox runs (in parallel!)”—Hynek makes a convincing argument for putting your packaged Python code in a src/ directory for ease of testing and coverage.
