What are some common mypy error messages I might encounter?

Some common mypy error messages include 'Incompatible types', 'Missing type hints', and 'Cannot find implementation'. Would you like to know how to fix them?

Yes, how do I fix the 'Incompatible types' error?

The 'Missing type hints' error indicates that you haven't provided type annotations for your function parameters or return types. You can resolve this by adding type hints to your function definitions.

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