Sorting
Definition and example
Sorting is the focus of this lesson. sorted(items) returns a new sorted list; items.sort() changes the original. The task asks you to apply that idea in a small example: Which call sorts in place. 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.
Submit your code to see results
Write your code in the middle column and press Run code.
Why this works
Checks on this task:
- The program output must match “[1, 2, 3]”.
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.
