Python中类的继承代码实例
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。
#!/usr/bin/python
#filename:pyclass.py
classMember:
def__init__(self,name,age):
self.name=name
self.age=age
print'Memberinit:%s'%self.name
deftell(self):
print'Name:%s,Age:%d'%(self.name,self.age),
classStudent(Member):
def__init__(self,name,age,marks):
Member.__init__(self,name,age)
self.marks=marks
print'Studentinit:%s'%self.name
deftell(self):
Member.tell(self)
print'Marks:%d'%self.marks
classTeacher(Member):
def__init__(self,name,age,salary):
Member.__init__(self,name,age)
self.salary=salary
print'Teacherinit:%s'%self.name
deftell(self):
Member.tell(self)
print'Salary:%d'%self.salary
s=Student('Tom',20,80)
t=Teacher('Mrs.Huang',30,50000)
members=[s,t]
formeminmembers:
mem.tell()
运行效果：
[root@localhosthhl]#pythonpyclass.py Memberinit:Tom Studentinit:Tom Memberinit:Mrs.Huang Teacherinit:Mrs.Huang Name:Tom,Age:20Marks:80 Name:Mrs.Huang,Age:30Salary:50000
我们同样编写同样效果的C++例子：
//filename:class.cpp
#include<string.h>
#include<iostream>
usingnamespacestd;
classMember
{
public:
Member(char*n,inta);
voidtell();
private:
charname[10];
intage;
};
Member::Member(char*n,inta)
{
memcpy(name,n,sizeof(name));
age=a;
cout<<"Memberinit:"<<name<<endl;
}
voidMember::tell()
{
cout<<"Name:"<<name<<","<<"Age:"<<age<<",";
}
classStudent:publicMember
{
public:
Student(char*n,inta,intm);
voidtell_s();
private:
intmarks;
};
Student::Student(char*n,inta,intm):Member(n,a)
{
marks=m;
cout<<"Studentinit:"<<n<<endl;
}
voidStudent::tell_s()
{
Member::tell();
cout<<"Marks:"<<marks<<endl;
}
classTeacher:publicMember
{
public:
Teacher(char*n,inta,ints);
voidtell_t();
private:
intsalary;
};
Teacher::Teacher(char*n,inta,ints):Member(n,a)
{
salary=s;
cout<<"Teacherinit:"<<n<<endl;
}
voidTeacher::tell_t()
{
Member::tell();
cout<<"Salary:"<<salary<<endl;
}
intmain(void)
{
Students("Tom",20,80);
Teachert("Mrs.Huang",30,50000);
s.tell_s();
t.tell_t();
return0;
}
运行效果：
[root@localhosthhl]#./class Memberinit:Tom Studentinit:Tom Memberinit:Mrs.Huang Teacherinit: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。。。
