Python class and inheritance

Compared with C ++, Python is simpler and more efficient. Below is a simple example of Python inheritance. Compared with C ++, Python is simpler and more efficient. Below is a simple example of Python inheritance.

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 ', 30,500 00)

Members = [s, t]

For mem in members:

Mem. tell ()

Running effect:

[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

We also write C ++ examples with the same effect:

# Include

# Include

Using namespace std;

Class Member

{

Public:

Member (char * n, int );

Void tell ();

Private:

Char name [10];

Int age;

};

Member: Member (char * n, int)

{

Memcpy (name, n, sizeof (name ));

Age =;

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,)

{

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,)

{

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", 30,500 00 );

S. tell_s ();

T. tell_t ();

Return 0;

}

Running effect:

[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

The two have the same running effect, but python is more concise...

The above is the explanation of Python class and inheritance. For more information, see PHP Chinese network (www.php1.cn )!
