Python中類的繼承代碼執行個體

相對於C++的繼承編寫，Python更簡潔，而且效率也是很高的，下面編寫一個簡單Python的繼承例子。

代碼如下:

#!/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()

運行效果：

代碼如下:

[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

我們同樣編寫同樣效果的C++例子：

代碼如下:

//filename: class.cpp
#include
#include
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:"<}

void Member::tell()
{
cout<<"Name:"<
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:"<}

void Student::tell_s()
{
Member::tell();
cout<<"Marks:"<}

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:"<}

void Teacher::tell_t()
{
Member::tell();
cout<<"Salary:"<}

int main(void)
{
Student s("Tom", 20, 80);
Teacher t("Mrs.Huang", 30, 50000);

s.tell_s();
t.tell_t();

return 0;
}

運行效果：

代碼如下:

[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

這兩者的運行效果是一樣的，但是python更簡潔些。。。
