First, the object-oriented Advanced Syntax section

　　static methods (@staticmethod)

Definition:　　 only nominal collation management, in fact, in a static method can not access the properties of the class or instance

　　

1 classDog (object):2     def __init__(self,name):3Self.name =name4 5 @staticmethod6     defEat (x,s):7         Print("%s is eating%s"%(x,s))8Dog.eat ("DF","fdasf")9"" DF isEating fdasf

　　class method (@classmethod)

Definition: class methods can access only class variables and cannot access instance variables

1 classDog (object):2Name ="444"3     def __init__(self,name):4Self.name =name5 6 @classmethod7     defEat (self):8         Print("%s is eating"%(self.name))9 TenD = Dog ("Zhangsan") One d.eat () A"" 444 isEating

　　Property Method (@property)

Definition: Turn a method into a static property

1 classDog (object):2     def __init__(self,name):3Self.name =name4 5 @property6     defEat (self):7         Print("%s is eating"%self.name)8 9D = Dog ("Zhangsan")Ten d.eat () One"" TypeError:'Nonetype'Object is  notCallable

1 correct method of invocation2 classDog (object):3     def __init__(self,name):4Self.name =name5 6 @property7     defEat (self):8         Print("%s is eating"%self.name)9 TenD = Dog ("Zhangsan") OneD.eat#eat Not added ()

　　Special members and methods of the class

　　1, __doc__, print the description of the class information

　　

1 classDog (object):2     " "3 Here is the description information4     " "5     def __init__(self,name):6Self.name =name7 8     defEat (self):9         Print("%s is eating"%self.name)Ten  One Print(Dog.)__doc__) A>>> here is a description of the information

2,__module__ and __class__
