Add proper Python code fences for syntax highlighting in README examples

[Programmer-RD-AI]

🐛 Problem

The Python examples in the README.md aren’t wrapped in triple backticks with the python language specifier. As a result:

• There’s no syntax highlighting, making the examples harder to read.
• Indentation and inline comments blend into the text, reducing clarity.

📋 Reproduction

1. Navigate to the project’s README.
2. Scroll to any of the “Python Examples” sections.
3. Observe that the code is rendered as plain text without highlighting.

✅ Expected Behavior

• All Python snippets should be fenced like so:

  ```python
  # Example code here

• This will enable syntax highlighting on GitHub, improving readability.

💡 Proposed Solution

1. Edit each code block in README.md to add ```python fences.
2. Verify rendering on GitHub’s preview.
3. Optionally, add a CI check or lint rule to ensure future examples include the correct fences.

📖 Additional Context

Improving syntax highlighting aligns with best practices for documentation and lowers the barrier for new contributors trying out the examples.
