[viveknair]

TLDR

Reformats Python code examples in README for better readability and consistency

Summary

This PR simplifies and standardizes the code formatting in the README.md file's Python examples. The changes focus on improving code readability by adding proper spacing between function definitions and ensuring consistent formatting throughout all code examples.

Key Changes

• Added blank lines between function definitions for better visual separation
• Reformatted inline code to improve readability (e.g., OpenAI chat completion calls)
• Ensured consistent spacing after decorators (@interaction, @traced, @eval)
• Maintained consistent formatting style across all code examples

Impact

• README.md documentation only
• No functional code changes
• Affects all Python code examples in the getting started and usage sections

Testing Considerations

• Verify that all code examples remain syntactically correct
• Ensure formatting changes don't break any copy-paste functionality for users
• Check that the examples still render properly in markdown viewers
