What are the best practices for documenting functions in code?

Best practices include using clear and concise comments, explaining parameters and return values, and maintaining consistency.

Can you give me an example of a well-documented function?

Sure! Here's an example:

def add(a: int, b: int) -> int:
    """
    Adds two integers and returns the result.

    Parameters:
    a (int): The first integer.
    b (int): The second integer.

    Returns:
    int: The sum of a and b.
    """
    return a + b

What tools can help with documenting code?

Tools like Sphinx, JSDoc, and Doxygen can automate documentation generation from your code comments.

How often should I update documentation?

Documentation should be updated whenever code changes are made, ideally as part of the development process.
