Lesson 3 — Let Python Summarize the Data

Level: Apprentice — roughly Grade 7 / ages 12–13 Duration: 25–30 minutes Format: Write real Python in the browser (runs instantly, nothing to install) Concept: Sum, maximum, average — basic statistics Python computes in one line, using lists from last unit

Learning Objective

Kids use sum, len, max on real data lists and compute an average — connecting loop/list skills to data work.

Do It Together (Parent-Child Co-participation)

Put the numbers from last lesson's survey table into a list and have your child compute total/max/average in code — you verify with a calculator. Who's faster?
