Learning goals

- Split a data problem into a small helper function and a loop function. - Use helper functions to transform or filter list data. - Work with lists of numbers, strings, and dictionaries. - Combine three small functions in the final stretch.

Part 4 is a bridge between basic function writing and larger program design. Most questions use two functions: one helper that handles one value or one dictionary, and one loop function that handles the full data set.
