python类和继承用法实例

本文实例讲述了python/' target='_blank'>python类和继承定义与用法。分享给大家供大家参考。具体如下：

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()

类继承如下：

#!/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()

希望本文所述对大家的Python程序设计有所帮助。
