PCPP1 Best Practices And Coding Conventions Practice Question

You are debugging a legacy application and need to ensure that resources like file handles are always closed. Which construct is preferred?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Use a context manager with the 'with' statement.

The 'with' statement (context manager) ensures that cleanup code is executed even if an exception occurs.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Wrap the file operation in a try-except block.

    Why it's wrong here

    This does not guarantee closure if an exception isn't caught or if the block is exited early.

  • Manually call file.close() in a finally block.

    Why it's wrong here

    While 'finally' works, the 'with' statement is more idiomatic and concise.

  • Use a context manager with the 'with' statement.

    Why this is correct

    This is the Pythonic way to handle resource management.

  • Rely on the garbage collector to close the handle.

    Why it's wrong here

    Garbage collection is non-deterministic and should not be relied upon for resource release.
