Definition and example
List methods is the focus of this lesson. append adds, pop removes, len counts. The task asks you to apply that idea in a small example: Which method adds to the end 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.
