Day 1/420: Python toolchain and interpreter choices
420 Day Python Production Track
Today I wanted python toolchain and interpreter choices to feel like a real engineering decision, not a syntax demo. The useful shift was turning python toolchain and interpreter choices into something I can explain from the code instead of memorizing from a tutorial.
The checks that mattered were interpreter version policy and what the repo actually runs, virtual environment and package isolation from day one, and tooling choices that keep local and CI behavior close.
The failure mode I was actively trying to avoid was letting convenience hide where state changes actually happen. I kept it tied to one realistic Python workflow so the lesson would sound like something I could defend in review instead of something I only recognized from a course.
That is the bar I want from this track: code that stays readable when requirements move, not just code that runs today.
