Question

When should a Python developer choose __name__ == '__main__' and Entry Points deliberately?

  1. Choose __name__ == '__main__' and Entry Points mainly when you want to postpone validation and fix issues manually later.
  2. Choose __name__ == '__main__' and Entry Points whenever you want the code to look more advanced, even if the design gets less clear.
  3. Choose __name__ == '__main__' and Entry Points only to avoid modeling the real data shape or domain contract explicitly.
  4. Use the __name__ guard for modules that should support both direct execution and import-based reuse.

Hint

Think about the production scenario where the choice genuinely improves the code.

Answer and rationale

Correct answer: D. Use the __name__ guard for modules that should support both direct execution and import-based reuse.

Use the __name__ guard for modules that should support both direct execution and import-based reuse. Interviewers often ask this to see whether you can connect the concept to real design decisions.
