Why Python needs static method staticmethod

編輯:Python

Static methods do not need attributes and other methods in the class , Why put it in a class ?

Because if you don't put it in the class, you have to put it outside alone , Not conducive to maintenance , You need to look everywhere when calling .

It can be understood as putting static methods in the module of class , But I don't want to instantiate classes , Because it consumes more resources , So allow direct access through classes .
