How do I set up MyPy for type checking in Python?

To set up MyPy, first install it using pip: pip install mypy. Then, you can add type hints to your Python code.

What are type hints and why should I use them?

Type hints are annotations that specify the expected data types of variables, function parameters, and return values. They help catch errors early.

Can you give me an example of using type hints?

Sure! Here's a simple example:

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

How do I run MyPy to check my code?

You can run MyPy by executing mypy your_script.py in the terminal. It will report any type errors found.
