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)
