相对于c++的继承编写，python更简洁，而且效率也是很高的，下面编写一个简单python的继承例子。
复制代码 代码如下:
#!/usr/bin/python
#filename: pyclass.py
class member:
def __init__(self, name, age):
self.name = name
self.age = age
print 'member init:%s' % self.name
def tell(self):
print 'name:%s,age:%d' % (self.name, self.age),
class student(member):
def __init__(self, name, age, marks):
member.__init__(self, name, age)
self.marks = marks
print 'student init:%s' % self.name
def tell(self):
member.tell(self)
print 'marks:%d' % self.marks
class teacher(member):
def __init__(self, name, age, salary):
member.__init__(self, name, age)
self.salary = salary
print 'teacher init:%s' % self.name
def tell(self):
member.tell(self)
print 'salary:%d' % self.salary
s = student('tom', 20, 80)
t = teacher('mrs.huang', 30, 50000)
members = [s, t]
for mem in members:
mem.tell()
运行效果：
复制代码 代码如下:
[root@localhost hhl]# python pyclass.py
member init:tom
student init:tom
member init:mrs.huang
teacher init:mrs.huang
name:tom,age:20 marks:80
name:mrs.huang,age:30 salary:50000
我们同样编写同样效果的c++例子：
复制代码 代码如下:
//filename: class.cpp
#include <string.h>
#include <iostream>
using namespace std;
class member
{
public:
member(char *n, int a);
void tell();
private:
char name[10];
int age;
};
member::member(char *n, int a)
{
memcpy(name, n, sizeof(name));
age = a;
cout<<"member init:"<<name<<endl;
}
void member::tell()
{
cout<<"name:"<<name<<","<<"age:"<<age<<",";
}
class student:public member
{
public:
student(char *n, int a, int m);
void tell_s();
private:
int marks;
};
student::student(char *n, int a, int m):member(n, a)
{
marks = m;
cout<<"student init:"<<n<<endl;
}
void student::tell_s()
{
member::tell();
cout<<"marks:"<<marks<<endl;
}
class teacher:public member
{
public:
teacher(char *n, int a, int s);
void tell_t();
private:
int salary;
};
teacher::teacher(char *n, int a, int s):member(n, a)
{
salary = s;
cout<<"teacher init:"<<n<<endl;
}
void teacher::tell_t()
{
member::tell();
cout<<"salary:"<<salary<<endl;
}
int main(void)
{
student s("tom", 20, 80);
teacher t("mrs.huang", 30, 50000);
s.tell_s();
t.tell_t();
return 0;
}
运行效果：
复制代码 代码如下:
[root@localhost hhl]# ./class
member init:tom
student init:tom
member init:mrs.huang
teacher init:mrs.huang
name:tom,age:20,marks:80
name:mrs.huang,age:30,salary:50000
这两者的运行效果是一样的，但是python更简洁些。。。
