Python Refresh / easy / Step 1 of 16
Practice stage
Core runtime habits
Hint
Normalize the boundary first, keep return shapes stable, and make the middle of the function boring on purpose.
Success criteria
- - Returns one stable shape across branches
- - Makes failure handling obvious
- - Keeps the core logic readable in under a minute
Review checklist
- - Did I make the input and output shapes explicit?
- - Would a teammate know where validation happens?
- - Did I avoid silent mutation or vague branching?
