Question

In Python, which comparison about __name__ == '__main__' and Entry Points is accurate?

  1. There is no practical difference in behavior, performance, or maintainability when __name__ == '__main__' and Entry Points is involved.
  2. The oldest option related to __name__ == '__main__' and Entry Points is always the right production choice regardless of workload or context.
  3. A guarded entrypoint separates reusable module code from executable script flow, while top-level side effects make imports riskier.
  4. Differences around __name__ == '__main__' and Entry Points are mostly cosmetic, so correctness and debugging quality do not really change.

Hint

Focus on the behavior or tradeoff, not just the keyword.

Answer and rationale

Correct answer: C. A guarded entrypoint separates reusable module code from executable script flow, while top-level side effects make imports riskier.

A guarded entrypoint separates reusable module code from executable script flow, while top-level side effects make imports riskier. This is the comparison that usually separates memorization from understanding.
