Looping over lists: Delivery Bike

Ride down a street of houses, and deliver to each one. A loop visits every item in a list.

What you'll learn

• Visiting every item
• Items and their numbers
• Only some items
• Building a new list
• Don't change a list while looping over it

Each idea opens with a short narrated video, about 2 minutes in all. Then you put it to work in the game.

The six levels

1. Every House Change it
2. Numbered Stops Copy and type
3. Even Side Only Fill the gap
4. Finished Stops Write it
5. Skipped Houses Fix it
6. Any Route Boss level

The levels go from changing one word, to writing the code on your own. The boss level changes every time you play.
