A mixin is a specific type of superclass, just called a mixin because of the concept it represents. A common type of mixin would be a class that defines some sort of modified functionality intended to be given to multiple, not necessarily related classes. Say you wanted all your classes to have a similar looking format when "print"ed. You could define a mixin class that defined a special __repr__ method. A detailed example of this is demonstrated in /Learning Python/ by Lutz & Ascher. There's no need to explicitly state that they are a mixin class, but if you felt the need to, you could either put it in a comment or, probably even better, in the mixin's docstring.
