Description of change

[docs] Make readme examples copy/paste possible by removing >>> and dding # to preserve output to preserve meaning

[Copilot]

Pull request overview

This PR improves the usability of README code examples by converting them from Python REPL format to plain executable Python code. The examples previously included >>> prompts which prevented direct copy/paste execution. By removing these prompts and converting output to comments, users can now copy examples directly into their code or Python files.

Key Changes:

• Removed Python REPL >>> prompts from all code examples
• Converted output lines to # comments to preserve expected results while maintaining executability
