Question

A developer asks Copilot Chat: "Write a function to validate email addresses." The output uses a naive regex, has no return-type annotation, and includes no docstring. The developer's team requires typed Python functions, Google-style docstrings, and rejection of addresses longer than 254 characters. Which single change to the prompt would most reliably produce output matching the team's requirements on the first attempt?

Accepted Answer

Explicitly state the constraints in the prompt: request a typed Python function with a Google-style docstring that also rejects addresses over 254 characters.

Answer

Send the same prompt several times and pick whichever response happens to include type hints and a docstring.

Answer

Add the word 'professional' and 'high-quality' before 'function' so Copilot infers the team's stricter standards.

Answer

Ask Copilot to first explain what makes a good email validator, then request the function in a separate unrelated prompt.
