What are some common mypy error examples?

Common mypy errors include 'Incompatible types', 'Missing return statement', and 'Argument type mismatch'. Would you like details on any specific error?

Can you explain the 'Incompatible types' error?

Sure! The 'Incompatible types' error occurs when a variable is assigned a value of a type that doesn't match its declared type. For example, if you declare a variable as an 'int' but assign it a 'str', mypy will raise this error.

How can I fix that error?

To fix it, ensure that the value assigned to the variable matches its declared type. You can also use type hints to clarify the expected types.

What about the 'Missing return statement' error?

The 'Missing return statement' error happens when a function is expected to return a value but doesn't. Make sure all code paths in the function return a value.
