How do I effectively document my Python code?

To effectively document your Python code, you should use docstrings, comments, and type hints. Docstrings provide a way to describe the purpose of a function or class, while comments can clarify complex logic. Type hints improve readability and help with type checking.

Can you give me an example of a docstring?

Sure! Here's an example of a docstring for a function:

def add(a: int, b: int) -> int:
    """
    Add two integers and return 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 are some best practices for writing comments?

Best practices for writing comments include:

1. Keep comments concise and relevant.
2. Avoid stating the obvious; instead, explain why something is done.
3. Update comments when you change the code to keep them accurate.

How can I use type hints in my code?

You can use type hints by specifying the expected data types of function parameters and return values. For example:

def greet(name: str) -> str:
    return f'Hello, {name}!'
