Project: a study scorecard
Lesson 12 of 20 · 18 min · Module 4: Reliable little programs
Build a small report from a set of learner records. This project combines conditions, loops, lists, dictionaries, and functions.

By the end, you’ll be able to…
- Translate a report specification into data operations
- Guard an empty average
- Return a consistent dictionary shape
The idea
Each record contains name and a numeric score. A passing score is at least 50. Reports should behave sensibly even when there are no records.
records = [
{"name": "Alex", "score": 80},
{"name": "Sam", "score": 40}
]01Write the output contract first
The report has exactly three roles: a count, an average, and a list of names. Work out one example by hand before writing the function.
02Test different kinds of records
Try mixed pass/fail scores, a score exactly equal to 50, all passing scores, and an empty input. A correct normal case alone does not guarantee a correct function.
Your project brief
study_report(records) to return a dictionary with count (all records), average (all scores, or 0 when empty), and passed (names scoring at least 50, in input order).What the checks look for
- Reports count, average, and passing names
- Handles the pass boundary
- Handles an empty collection
- Preserves input order
Take this with you
Combine small operations around a clear contract, and make edge cases part of the design.
