Note that super() is implemented as part of the binding process for explicit dotted attribute lookups such as super().getitem(name). It does so by implementing its own getattribute() method for searching classes in a predictable order that supports cooperative multiple inheritance. Accordingly, sup...

当方法需要传入当前的类名,返回值又和当前类名绑定,此时应该选择 class method。 当进行一些类相关的操作,但是又不需要绑定类名,此时应该选择 static method。 You can use class methods for any methods that are not bound to a specific instance but the class. In practice, you often use class methods ...

The__new__method in Python is a static method and constructor that creates and returns a new instance (object) of a class.__new__is often used to help control the creation of objects, and is called before using__init__. What is the difference between __init__ and __new__?
