Detailed description of Python class inheritance instances and python inheritance instances

Python class inheritance

Since Python is object-oriented, it certainly supports class inheritance. the inheritance of Python implementation classes is simpler than that of Javascript.

Parent class:

class Parent:    parentAttr = 100    def __init__(self):     print("parent Init")    def parentMethod(self):     print("parentMethod")      def setAttr(self,attr):     self.parentAttr = attr    def getAttr(self):     print("ParentAttr:",Parent.parentAttr) 

Child class

class Child(Parent):    def __init__(self):     print("child init")    def childMethod(self):     print("childMethod") 

Call

p1 = Parent(); p1.parentMethod();  c1 = Child(); c1.childMethod(); 

Output:

parent Init parentMethod child init childMethod Press any key to continue . . . 

Python supports multi-Inheritance

Class A: # define class ..... class B: # define class B ..... class C (A, B): # inherit classes A and B .....
