What is PEP 257 and how does it relate to Python projects?

PEP 257 is the Python Enhancement Proposal that provides conventions for writing docstrings in Python. It helps maintain consistency and clarity in documentation.

Why is it important to follow PEP 257 guidelines?

Following PEP 257 guidelines ensures that your code is well-documented, making it easier for others (and yourself) to understand and maintain it.

Can you give me an example of a good docstring?

Sure! Here's an example:

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

    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

How can I check if my docstrings comply with PEP 257?

You can use tools like pydocstyle or flake8-docstrings to check your docstrings for compliance with PEP 257.
