What is method documentation and why is it important?

Method documentation refers to the detailed description of a method's purpose, parameters, return values, and usage. It's crucial for understanding and maintaining code.

Can you give me an example of how to document a method?

Sure! For a method that adds two numbers, you might document it like this:

def add(a: int, b: int) -> int:
    """
    Adds two integers.
    
    Parameters:
    a (int): The first number.
    b (int): The second number.
    
    Returns:
    int: The sum of a and b.
    """
    return a + b

What tools can I use for method documentation?

There are several tools available, such as Javadoc for Java, Sphinx for Python, and Doxygen for C++. These tools help automate the documentation process.

How often should I update my method documentation?

You should update your method documentation whenever you make changes to the method's functionality, parameters, or return values to ensure it remains accurate.
