## Purpose
This document provides instructions for GitHub Copilot to follow PEP 8 standards when generating Python code. These guidelines ensure the code is clean, readable, and adheres to widely accepted Python best practices.

## General Guidelines
1. Follow the [PEP 8](https://peps.python.org/pep-0008/) style guide strictly.
2. Ensure all generated code uses 4 spaces per indentation level.
3. Line length should not exceed 79 characters.
4. Include proper documentation for all classes, methods, and functions (docstrings).
5. Avoid trailing whitespace at the end of lines.

## Naming Conventions
- Use `snake_case` for variables, functions, and method names.
- Use `PascalCase` for class names.
- Constants should be in `ALL_CAPS`.

## Import Statements
- Always place import statements at the top of the file.
- Group imports in the following order:
  1. Standard library imports
  2. Related third-party imports
  3. Local application/library-specific imports
- Use one import per line.
- Avoid wildcard imports (`from module import *`) and prefer explicit imports.
