Python class and inheritance usage instance, python usage instance

This example describes the definition and usage of python classes and inheritance. Share it with you for your reference. The details are as follows:

class Employee:  passlee = Employee()lee.name = 'leefang'lee.age = 28

class cAA:  i = 8  def __init__(self):    self.__a = 7    self.m_a = 1    self.m_b = 2  def __Method1(self):    self.__a += 1    return self.__a  def Method2(self, _x):    print self.__Method1(), _xclass cCC:  def Method2(self,_x):    print 'aaaaaaaaa'class cBB(cCC, cAA):  def kk(self, _x):    self.Method2(_x)  def tt(self):    print self.m_aa = cAA()a.Method2(3)print a.m_ab = cBB()b.Method2(4)b.kk('ffffff')b.tt()

Class inheritance:

#!/usr/bin/pythonclass Oneclass:  def setdata(self,value):    self.data = value  def display(self):    print self.dataclass Twoclass(Oneclass):  def display(self):    print "current value is %s" % self.dataclass Threeclass(Twoclass):  def __init__(self,value):    self.data = value  def __add__(self,other1):    self.data = self.data + other1  def __mul__(self,other2):    self.data = self.data * other2object1 = Oneclass()object1.setdata(1234)object1.display()object2 = Twoclass()object2.setdata(1234)object2.display()object3 = Threeclass(12)object3.display()object3.setdata(1234)object3.display()object3 + 22object3.display()object3 * 10object3.display()

I hope this article will help you with Python programming.
