Chapter 54 Quiz

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

• Write a try/except/else block: Catch a specific exception type and handle the success path separately
• Raise an exception with a message: Use raise ValueError(f"...") with an f-string that includes the bad value
• Choose the right exception type: Given a scenario, pick ValueError, TypeError, KeyError, or FileNotFoundError
• Explain what finally does: Describe when the finally block runs and why it exists
• Use with open to read a file: Load JSON data from a file with guaranteed cleanup
• Write isinstance checks: Validate a dictionary field's type and value before using it

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

Test your understanding of Python's error handling by solving real-world scenarios involving try/except, raising exceptions, the hierarchy, resource safety, and manual validation.
