All 3 tests pass now. `test_quantity` was failing because `total()` in `cart.py` added up the prices but ignored the quantity. I changed it to `sum(price * qty ...)`. I did not change the tests.

Ran `python3 test_cart.py`. It failed on `test_quantity`. The cause was that `total()` in `cart.py` added up the prices and ignored the quantities. I changed the sum to `price * qty`. Re-running the tests now prints "all tests pass" and exits with code 0.
