Python Class: Object-oriented advanced programming @property

I can't read it, I'll record it.

One

#!/usr/bin/env Python3
#-*-Coding:utf-8-*-

Class Student (object):

@property
DEF score (self):
Return Self._score

@score. Setter #setter是哪里来的?? Role???
DEF score (self, value):
If not isinstance (value, int):
Raise ValueError (' score must is an integer! ')
If value < 0 or value > 100:
Raise ValueError (' score must between 0 ~ 100! ')
Self._score = value

s = Student ()
S.score = 60
Print S.score

Run Result: 60

Two

#!/usr/bin/env Python3
#-*-Coding:utf-8-*-

Class Student1 (object):

@property #????
def birth (self):
Return Self._birth

@birth. Setter #????
def birth (self, value):
Self._birth = value

@property #????
def age (self):
Return 2014-self._birth

s = Student1 ()
S.birth = 60
Print S.age
