name: python-script description: When writing Python scripts, always include author information header.

When writing a Python script, always include the following header at the top of the file:

1. Author information block: Include a docstring or comment block with:

   • Author: Zehao Lu
   • Email: luzehao1998@gmail.com
   • Date created
   • Brief description of the script

2. Use this format:

Copy#!/usr/bin/env python3
"""
Author: Zehao Lu
Email: luzehao1998@gmail.com
Date: [YYYY-MM-DD]
Description: [Brief description of what this script does]
"""

1. Additional guidelines:
   • Include #!/usr/bin/env python3 shebang for executable scripts
   • Add type hints where appropriate
   • Include a if __name__ == "__main__": block for scripts meant to be run directly

Example

A script to calculate fibonacci numbers:

Copy#!/usr/bin/env python3
"""
Author: Zehao Lu
Email: luzehao1998@gmail.com
Date: 2026-01-21
Description: Calculate and print fibonacci numbers up to a given limit.
"""

def fibonacci(n: int) -> list[int]:
    """Generate fibonacci sequence up to n numbers."""
    if n <= 0:
        return []
    if n == 1:
        return [0]

    fib = [0, 1]
    while len(fib) < n:
        fib.append(fib[-1] + fib[-2])
    return fib


if __name__ == "__main__":
    result = fibonacci(10)
    print(f"Fibonacci sequence: {result}")
