一,self含义
# -*- coding: utf-8 -*- class person: def one(self,name,age): print "you name is %s and you age is %s." % (name, age) p = person() #绑定实例 p.one("du",22)
执行结果:
you name is du and you age is 22.
其实self可以不必写成self,但是必须要有一个参数如下图
详细了解可以参考博客:http://www.cnblogs.com/jessonluo/p/4717140.html
二,__init__初始化。
# -*- coding: utf-8 -*- class person: def __init__(self,sex): self.sex = sex def one(self,name,age): print "you name is %s and you age is %s and sex is %s" % (name, age, self.sex) p = person("boy") #绑定实例 p.one("du",22)
执行结果:
you name is du and you age is 22 and sex is boy
其实就相当于变量sex在类里。比函数大一级别。如下面的程序,和上面的执行结果是一样的。
# -*- coding: utf-8 -*- class person: sex = "boy" def __init__(self,sex): #self.sex = sex pass def one(self,name,age): print "you name is %s and you age is %s and sex is %s" % (name, age, self.sex) p = person("boy") #绑定实例 p.one("du",22)
