What are the differences between Python type hints and comments?

Python type hints are a way to indicate the expected data types of variables, function parameters, and return values, while comments are used to explain code or provide context without affecting the code's execution.

Can you give me an example of type hints in a function?

Sure! Here's a simple example:

def add_numbers(a: int, b: int) -> int:
    return a + b

In this function, a and b are expected to be integers, and the function returns an integer.

What are the benefits of using type hints?

Type hints improve code readability, help with static type checking, and can enhance IDE features like autocompletion and error detection.

Are there any downsides to using type hints?

One downside is that they can make the code more verbose. Additionally, type hints are optional, so they may not be consistently used across a codebase.
