Python AttributeError异常

遇到一个很奇怪的问题，本人刚学习Python ,在学类与对象的方法时，在调用方法时，我的对象名取名为k ，然而死活就是报AttributeError异常; 在反复检查代码无误后，然后我试着改一下名字，奇迹出现了，名字一改就好了，我以为不能使用单个字母，抱着试一试的心态，我将对象名改为a ,奇迹再次出现，成功了！！！规则不是很懂，还请大神指教nn```n class Person:n population=0n def __init__(self,name):n self.name=namen print '(Initializing %s)'%self.namen Person.population+=1n def __del__(self):n print'%s says bye.'%self.namen Person.population-=1n if Person.population==0:n print 'I am the last one.'n else:n print 'There are still %d people left.'% Person.populationn def sayHi(self):n print 'Hi,my name is %s.' % self.namen def howMany(self):n if Person.population==1:n print 'I am the only person here.'n else :n print 'We have %d persons here.' % Person.populationnswaroop=Person('swaroop')nswaroop.sayHi()nswaroop.howMany()nn# 此处有问题 na=Person('Abdul Kalam')na.sayHi()na.howMany()nnswaroop.sayHi()nswaroop.howMany()n```nn

Python出现属性错误（Attributeerror）的原因之一

检查类中构造函数__init__（）是否写正确，左右两边各两条下划线

python AttributeError： _exit_ 这是什么错误

python AttributeError： _exit_ 这是什么错误

Python中的AttributeError错误的常见原因

常见的原因如下： 类构造函数出了问题，本来是init()函数，但有几个类的构造函数成了_init，少了一个’_’符号 缩进不正确，把空格当做tab。

_THROW 何解？
