这篇文章主要介绍了python类和继承用法,实例分析了Python类的定义与继承的实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了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:

									  pass

									lee = 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(), _x

									class cCC:

									  def Method2(self,_x):

									    print 'aaaaaaaaa'

									class cBB(cCC, cAA):

									  def kk(self, _x):

									    self.Method2(_x)

									  def tt(self):

									    print self.m_a

									a = cAA()

									a.Method2(3)

									print a.m_a

									b = cBB()

									b.Method2(4)

									b.kk('ffffff')

									b.tt()

类继承如下：

									#!/usr/bin/python

									class Oneclass:

									  def setdata(self,value):

									    self.data = value

									  def display(self):

									    print self.data

									class Twoclass(Oneclass):

									  def display(self):

									    print "current value is %s" % self.data

									class 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 * other2

									object1 = Oneclass()

									object1.setdata(1234)

									object1.display()

									object2 = Twoclass()

									object2.setdata(1234)

									object2.display()

									object3 = Threeclass(12)

									object3.display()

									object3.setdata(1234)

									object3.display()

									object3 + 22

									object3.display()

									object3 * 10

									object3.display()
