How do I set up mypy annotations in my Python project?

To set up mypy annotations, first install mypy using pip: pip install mypy. Then, add type hints to your Python code.

What are type hints and why should I use them?

Type hints are a way to indicate the expected data types of variables, function parameters, and return values. They help with code clarity and enable static type checking.

Can you give me an example of how to use 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 your terminal. It will check for type errors based on your annotations.
