Question

Which statement about __name__ == '__main__' and Entry Points is the strongest interview answer?

  1. __name__ == '__main__' and Entry Points is mostly a naming style choice and has little effect on runtime behavior or design tradeoffs.
  2. The __name__ guard keeps a module importable without automatically running script-only behavior at import time.
  3. __name__ == '__main__' and Entry Points exists mainly to reduce the number of files in a Python project.
  4. __name__ == '__main__' and Entry Points matters only for frontend scripting and not for backend or automation code.

Hint

Start with the core rule behind __name__ == '__main__' and Entry Points.

Answer and rationale

Correct answer: B. The __name__ guard keeps a module importable without automatically running script-only behavior at import time.

The __name__ guard keeps a module importable without automatically running script-only behavior at import time. This is the base concept interviewers commonly test first.
