Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the type errors pattern
Totals that concatenate, sorts that put 10 before 9, comparisons that refuse to run.
What went wrong: // is whole-number division. It drops the decimal part, so 3 // 2 is 1, not 1.5.
The fix: return sum(nums) / len(nums)
Remember: / gives the exact result, // rounds down to a whole number.
The pattern behind it: type errors.
