Inheritance of the Python class Detailed explanation

Since Python is

object-oriented, of course it supports class inheritance. Python implements class inheritance simpler thanJavascript.

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 multiple inheritance

class A:    # 定义类 A 
..... 
 
class B:     # 定义类 B 
..... 
 
class C(A, B):  # 继承类 A 和 B 
.....
