python-类操作

格式：
class 类名:
   
    成员变量
    __privateMenber =
  
    def __init__(self,args):  #构造函数
         内容
 
    def method1(self,args):
        内容

    def __privateMethod(self,args):
        内容

     def __del__(self): #析构函数
         内容
  
-------------------------------------------------------------------------------------------------------
eg:

class Student:
  
      name = 'Tom'
    
      age = '23'

      gender = 'male'

      def __init__(self, name, age, gender):

            self.name = name

            self.age = age

            self.gender = gender

      def getName(self):

            return self.name

       def getAge(self):

            return self.age

        def getGender(self):

            return self.gender

       def __del__(self):
            
            print 'this is a distruction function'


stu = Student('wuyn', '23', 'female')

print stu.getName()

print stu.getAge()

print stu.getGender()

类的继承，class ClassName(BaseClass):

class SubClass(BaseClass):
     
        def __init__(self,args):
           
              BaseClass.__init__(args)

              self.arg = arg

        def __del__(self):
           
              ……

eg:

       class SchoolStudent(Student):

             def __init__(self, school, name, age, gender):
    
                   Student.__init__(self,name,age,gender)

                   self.school = school

             def getSchool(self):
          
                   return self.school

             def __del__(self):

                   print 'SchoolClass construction function'


sStu = ('STU', 'Wuyn', '24', 'male')

print sStu.getName()

print sStu.getAge()

print sStu.getGender()

print sStu.getSchool()

python 类不支持多继承，不支持函数重载，可以通过函数覆盖实现多态。
