I've recently come across a use of multiple inheritance in some python code that shows me why this is multiple inheritance is a bad thing. It seems to break the OOP concept of encapsulation.

I basically want to do multiple inheritance with mixins. No, you probably don't. Some degree of "IMO" here, but in C++, multiple inheritance is generally an indicator of flawed design.

Multiple interface inheritance allows an object to inherit many different method signatures with the caveat that the inheriting object must implement those inherited methods.
