python类和继承用法 python类和继承用法实例
defias 人气:0想了解python类和继承用法实例的相关内容吗，defias在本文为您仔细讲解python类和继承用法的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：python,类,继承，下面大家一起来学习吧。
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()
希望本文所述对大家的Python程序设计有所帮助。
