Code Readability Enhancement

[mandlinsarah]

This update improves the readability and formatting of example_chat_completion.py without impacting its core functionality. It ensures that the code conforms to PEP 8 style guidelines.

In the provided script, there is a small syntax issue at the end. The closing brace } after fire.Fire(main) is unnecessary and should be removed, as it doesn't match any opening brace.

So, the corrected final part should look like:

if name == "main":
fire.Fire(main)
