Write down the input contract and the failure cases before coding.
local runtime
RUNTIME OUTPUT
Use your Python runtime locally, then compare with solution.py.
Use your local runtime, then review the reference solution
LEARN FROM THE SOLUTION
Why the solution works.
type(score) is int intentionally excludes bool, because bool is a subclass of int in Python. Building a fresh dictionary makes the function safe to reuse in code that still needs the original input.
What this exercise teaches
Dictionary access
Type checks
Pure functions
A PRACTICAL PLAN
Work through Validate structured records with intent.
Translate the contract.Turn the requirements into a short checklist before editing your-solution.py.
Use the example as evidence.Predict the result for the supplied input, then add one boundary case such as an empty value, a limit, or unexpected input.
Review the implementation.Compare your choices against solution.py only after a real attempt.
EXERCISE FAQ
Before you move on.
What does “Validate structured records” teach?
This intermediate Python exercise focuses on Dictionary access, Type checks, Pure functions. Its requirements define the exact behavior to implement before you write code.
How should I validate this Python solution?
Start with the displayed example input and expected output, then test a boundary case suggested by the requirements. Write and compile the starter in your local Python environment, exercise the example and edge cases, then compare your approach with solution.py.
When should I open the reference solution?
Attempt Validate structured records first. Then open the read-only solution file to compare the contract, edge-case handling, and implementation choices—not simply to copy the final code.
