Ignoring errors with MyPy should be a precise, surgical process, not a broad suppression. The most effective way to handle known, persistent issues (like dynamically assigned attributes or known type inconsistencies in third-party libraries) is by using the # type: ignore comment combined with the exact MyPy Error Code.

An experienced developer always aims for the narrowest possible scope of suppression to maintain maximum type-checking coverage across the rest of the codebase.

When integrating MyPy into a large or legacy Python codebase, or when dealing with highly dynamic code, you will inevitably encounter situations where MyPy raises valid errors that you cannot (or should not) fix immediately. In these cases, selectively ignoring errors becomes a vital skill.

A super experienced developer never ignores errors blindly; they use these mechanisms strategically to maintain the highest possible type-checking quality in the rest of the codebase.

Here is a deep dive into the various methods MyPy provides for ignoring errors, from the narrowest to the broadest scope.
