How do I set up Docker for Python in VS Code?

Grab Docker Desktop, install VS Code's Dev Containers extension. Add Dockerfile and devcontainer.json as above. Reopen folder in container. That's it—no rituals required.

Does Docker slow down Python development?

Nah. First build takes a minute; rebuilds are seconds with caching. VS Code feels identical—faster debugging, even, since envs match.

Is Docker necessary for small Python teams?

Yes. 'Works on my machine' hits solos too—six months from now, when you're debugging old code. Prevention beats cure. Word count: 1027.
