What is MyPy and how do I use it in Python?

MyPy is a static type checker for Python that helps you catch type errors before runtime. You can use it by adding type hints to your code.

Can you give me an example of how to add type hints?

Sure! For example, you can define a function like this:

def greet(name: str) -> str:
    return f'Hello, {name}!'
``` This specifies that `name` should be a string and the function returns a string.

What are the benefits of using MyPy?

Using MyPy can help improve code quality, catch bugs early, and make your code more understandable by providing clear type information.

Is MyPy compatible with all Python versions?

MyPy is compatible with Python 3.5 and later versions. It's best to use it with the latest version of Python for optimal features.
