相對(duì)于c++的繼承編寫，python更簡(jiǎn)潔，而且效率也是很高的，下面編寫一個(gè)簡(jiǎn)單python的繼承例子。

class?Member: ??

????????def?__init__(self,?name,?age): ??

????????????????self.name?=?name ??

????????????????self.age?=?age ??

立即學(xué)習(xí)“Python免費(fèi)學(xué)習(xí)筆記（深入）”；

????????????????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(yùn)行效果：

[root@localhost?hhl]??

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：

#include?<string.h> ??

#include?<iostream> ??

using?namespace?std; ??

class?Member ??

{ ??

????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; ??

}??

運(yùn)行效果：

[root@localhost?hhl]??

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(yùn)行效果是一樣的，但是python更簡(jiǎn)潔些。。。
