Child class execution Parent class constructor method

• Subclasses sometimes need to execute the parent class's constructor method

Class Annimal (object):    def __init__ (self):        print (' bar ')        self.type = ' Animal ' class Shengwu (object):    def _ _init__ (self):        print (' Sengwu ')        self.tc = ' Creature ' class Cat (Annimal,shengwu):        def __init__ (self):            SELF.N = ' Mao '            Super (cat,self). __init__ () m = Cat () print (m.__dict__)

The Cat class inherits the Annimal class and the Shengwu class, and in the construction method of the Cat class executes the construction method of the parent class super (cat,self). __init__ (), so the result:

However, the execution of the parent class is constructed by simply executing the Annimal __init__ () method, which does not implement the Shegnwu constructor method. This is identical to the order in which the inherited parent class executes the method in the parent class.
