一个问题哦，有一个问件有若干行，每行由四个项组成，由空格分开。我想把每行按照第一项进行排序，怎么弄啊？每行第一项都是汉字串。
例如：

俊杰 jun4jie2 n 1
俊美 jun4mei3 a 0
俊俏 juan4qiao4 a 2
俊秀 juan4xiu4 a 1

排序……

建一个 data.txt，把数据放到里面就行了。
（恕我直言）最近发现组里（相对于我的）新手不少，自己信心倍增
顺便提个建议，这样的问题我个人认为还是放到 comp.lang.python 或 
cn.bbs.comp.lang.python（如果你英语实在不行）这样热闹的地方去提比较好。

下面的一段代码是从《简明Python教程》里面摘取出来的一个sample【问题的产生跟摘
取没有关系】。有个奇怪的问题，下面代码部分标记红色的变量使用不同的变量时会报
错！
如使用"karlm"、"f"等变量名时运行正常，但是使用"klarm"、"ff"、"fk"等时运行程
序会报错：
Exception exceptions.AttributeError: "'NoneType' object has no attribute
'population'" in <__main__.Person instance
at 0xb7c413cc>> ignored
没搞明白什么原因，哪位大虾指点一下！！


#!/usr/bin/python
class Person:
    population = 0
    def __init__(self, name):
        self.name = name
        print '(Initializing %s)' % self.name
        Person.population += 1

    def __del__(self):
        print '%s says bye.' % self.name
        Person.population -= 1
        if Person.population == 0:
            print 'I am the last one.'
        else:
            print 'There are still %d people left.' % Person.population

if __name__ == "__main__":
        swaroop = Person('Swaroop')
        karlm = Person('Abdul Kalam')
