Recap: Supply Run

Combine string methods, lists, looping over lists, and break/continue

Mission: Supply Run

The station receives a list of supply crates named items (already on the right). Some crates are contaminated: their name starts with con-. Sort the good supplies into a clean list with these rules:

1. Loop through the items.
2. Skip any crate whose first four characters are con-
3. For every good crate, add it to a new list called clean
4. The moment you add butter, the bay is full, so stop right after adding it
5. Print each item in clean, one per line
6. Print Total: then how many items ended up in clean

Output

milk
bread
cheese
butter
Total: 4

The two con- crates are skipped, and the loop stops as soon as butter is added, so jam is never reached.
