Question

What deeper point about __name__ == '__main__' and Entry Points should a senior Python developer mention?

  1. At senior level, the right answer is that __name__ == '__main__' and Entry Points exists mostly for historical syntax reasons.
  2. Senior answers connect entrypoint discipline to testability, import safety, and predictable startup behavior.
  3. At senior level, Python removes the tradeoffs around __name__ == '__main__' and Entry Points, so design choices barely matter in practice.
  4. At senior level, any approach to __name__ == '__main__' and Entry Points is equally correct if it passes one small local test.

Hint

Look beyond syntax and explain the runtime, API, or design consequence.

Answer and rationale

Correct answer: B. Senior answers connect entrypoint discipline to testability, import safety, and predictable startup behavior.

Senior answers connect entrypoint discipline to testability, import safety, and predictable startup behavior. This is the kind of tradeoff-aware answer senior interviews usually expect.
