Python common method, @classmethod, @staticmethod

• Common methods
  Instantiate a class and then invoke the method through instantiation of the class:

  class method1:def__init__(self):    self= [1,2,3,]def getvalue(self):    returnself.items

• @classmedhod
  Dependency class instead of an example, the first parameter that defines the method is the current class

  class  method2:item =  1  def  __init__  (self ): self . Items =  [1< /span>,2 , 3 ,] @classmethod  def  GetValue (CLS, args): print  (cls. __name__ ) # print:method2  print  (Cls.item) # print:1  return  cls  

• @staticmedhot
  Static methods, which are consistent with Java, C #, are defined only in classes, and are not related to classes

  class method3:item  =1@staticmethoddef getvalue():    print(item)      # error
