6.Use AI as an Email Assistant

Lab Information The nautilus AI Development Team is now working on automating written communication tasks. As part of this initiative, you are required to build a Python-based AI Email Assistant that rewrites messages into polite and professional emails. Inside email_assistant.py, create an OpenAI client using the provided API key and base URL under /root/.bash_profile. Then, define a function named rewrite_email(text: str) -> str that constructs a parameterized prompt asking the AI to rewrite the given email text politely and professionally.
