Don't Cross The Streams - An Introduction to Virtual Environments
summary
Covers concrete commands and gotchas: use pip install, avoid sudo pip install and prefer pip install --user; capture deps with pip freeze -> requirements.txt and restore with pip install -r requirements.txt; create isolated interpreters with virtualenv (virtualenv --python=...) which copies a Python into a folder and uses local site-packages when activated; activate via Scripts\activate on Windows or source bin/activate on macOS/Linux; dependency resolution is first-found so consider Conda or higher-level tools for binary/non‑pure‑Python stacks.
