For work needs, I’m learning python these days. When I met multiple inheritance, I felt a little bit confused.

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

Singleton is a creational design pattern that lets you ensure that a class has only one instance, while providing a global access point to this instance.

Builder is a creational design pattern that lets you construct complex objects step by step. The pattern allows you to produce different types and representations of an object using the same construction code.

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.
