What is the difference between mypy annotations and type checking?

Mypy annotations are type hints in Python code, while type checking is the process of verifying those hints.

Can you give me an example of how to use mypy annotations?

Sure! You can annotate a function like this: def greet(name: str) -> str:. This indicates that name should be a string.

How does mypy perform type checking?

Mypy checks your code against the annotations you provided, ensuring that the types match during static analysis.

Are there any benefits to using mypy annotations?

Yes, they improve code readability, help catch errors early, and enhance IDE support for autocompletion.
