Lists
Definition and example
Lists is the focus of this lesson. A list holds many values in order: fees = [9000, 11667]. The task asks you to apply that idea in a small example: How do you read the first item of a list. Before you run the code, predict what should happen. Then Inspect the printed output and the values your program uses and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
Run your code to see the output and the checks.

Why this works
Checks on this task:
- The program output must match “9000”.
The task and step-by-step instructions are written as comments at the top of the editor. Change one relevant line, run it, and compare the result with these checks.
