Chapter 61 Quiz

Before taking the quiz, verify that you can do each of these without looking at the lessons:

  • Replace a stored field with @property and explain why the interface does not break
  • Write a @classmethod factory that uses cls(...) and explain why not ClassName(...)
  • Write a custom decorator with functools.wraps and explain the wrapping mechanism
  • Define a Protocol and write a class that satisfies it without inheritance
  • Explain when to use Protocol vs ABC

If any feel uncertain, revisit the specific lesson before continuing.

Test your understanding of properties, static and class methods, custom decorators, and Protocols by evaluating design decisions, tracing decorator behavior, analyzing Protocol compliance, and applying advanced patterns to class design.

TDG Extension

After completing the quiz, try /tdg in Claude Code to extend your SmartNotes architecture with a new pattern. Example: add a @cache_result decorator that memoizes expensive property computations.
