Python Special Syntax 7:继承

继续在上一节的类的基础上测试继承：

#-*-coding:utf-8
import  Syntax2

class Student(Syntax2.Person):
    def __init__(self,name,age):
        Syntax2.Person.__init__(self,name)
        Syntax2.Person.printName(self)
        print('age %s' % age)
        self.age=age


    def detail(self):
        print('Name %s, age:%d',(self.name,self.age))



stu=Student('zhangsan',19)
stu.detail()

print(Syntax2.Person.count)
print(stu.count)

输出：

I'm importing by some other guys.
zhangsan has been created
Name is zhangsan
age 19
('Name %s, age:%d', ('zhangsan', 19))
2
1

 

接着看多继承，这个跟C#有很大的区别

 

#-*-coding:utf-8
import  Syntax2

class Student(Syntax2.Person,list):
    def __init__(self,name,age):
        Syntax2.Person.__init__(self,name)
        Syntax2.Person.printName(self)
        print('age %s' % age)
        self.age=age


    def detail(self):
        print('Name %s, age:%d',(self.name,self.age))



stu=Student('zhangsan',19)
stu.detail()

print(Syntax2.Person.count)
print(stu.count)

stu.append('item1')
stu.append('item2')

for i in stu:
    print('Member: %s' % i),


输出：

I'm importing by some other guys.
zhangsan has been created
Name is zhangsan
age 19
('Name %s, age:%d', ('zhangsan', 19))
2
1
Member: item1 Member: item2

注意上述代码块中的append方法以及foreach，这个多继承让我真的是有些半天合不拢嘴，工作这么多年就没玩过多继承……！
