Environments and dependencies

A virtual environment keeps a project's packages separate. Requirements pin exact versions so another machine installs the same set.

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
pip install requests==2.32.3
pip freeze > requirements.txt
