2.7. Chapter Exercise

Apply the key ideas from this chapter in the connected task below. Work in your own notebook or local project. Keep your implementation, reasoning, and verification results together.

2.7.1. Build a small Python analysis

1. Reuse a short list of records or values from this chapter. Write a function that uses variables, conversion, decisions, and iteration to compute a labeled result.

2. Use lists, strings, and a dictionary for distinct roles, documenting each function’s parameters and return value.

3. Check an empty list, repeated categories, and a boundary value. Trace one record through the calculation and verify the report against a manual calculation before interpreting it.
