Git subtree allows you to split directories out with their own git history.

mkdir subtree && cd subtree && git init
mkdir lib && mkdir src
touch lib/__init__.py && touch src/__init__.py
printf 'def add(a, b):\n    return a+b\n' > lib/add.py
printf 'from lib.add import add\nprint add(1, 4)\n' > src/secret_stuff.py
git add . && git commit -m "We have a super cool adder"

So now running "python src/secret_stuff.py" we can see our super cool 5 printed out.
