How do I document a Python function?

To document a Python function, you can use a docstring right after the function definition. It should describe what the function does, its parameters, and its return value.

Can you show me an example of a function with a docstring?

Sure! Here's an example:

def add(a, b):
    """
    Adds two numbers together.

    Parameters:
    a (int or float): The first number.
    b (int or float): The second number.

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

What if my function has multiple parameters?

You can still document each parameter in the docstring. Just list them all with their types and descriptions.

Is there a specific format I should follow for the docstring?

Yes, it's common to follow the PEP 257 conventions for docstrings, which recommend using triple quotes and including sections for parameters and return values.
