Python中类的继承代码实例

这篇文章主要介绍了Python中类的继承代码实例,本文直接给出代码及运行效果,需要的朋友可以参考下

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。

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：

代码如下:
//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:"<<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：

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。。。
