The Challenge
Scenario: /home/labuser/lab/transform.py should collect the squares of every even number from 1 to 20, but the logic to filter and square them was never written.
Task: Fix transform.py using a list comprehension so squares.txt contains 4,16,36,64,100,144,196,256,324,400. Run check when ready.
