The __eq__ method should only be included when a comparison for equality uses criterion other than object identity. If object identity is the desired criterion, the default implementation will suffice. It is not necessary to include __eq__ just because the class will be exported as part of a module. And __eq__ should not be included in every class, as many classes do not have a concept of equality beyond object identity.
