As was mentioned in the introduction, one of the core features of Python is that everything is an object, and as such, they can all be treated equally. This means that there are no special distinctions of things that we can or cannot do with classes, functions, or custom objects. They can all be passed by parameter, assigned, and so on.

It is for this reason that many of the factory patterns are not really needed. We could just simply define a function that will construct a set of objects, and we can even pass the class that we want to create by a parameter.
