There many advanced techniques that we didn’t cover: Multiple inheritance (deriving from multiple classes) can create a real mess.

inheritance etc. advanced definition that some OOP languages don’t have. • The advantages for Python to use design pattern is that it supports dynamic type binding. In other words, an object is rarely only one instance of a class, it can be dynamically changed at runtime. • But Python might ignore a basic regulation of OOP: data and
