用python实现两个文本合并

一段时间前在网上看到一段面试题，要求如下：

employee文件中记录了工号和姓名

cat employee.txt:

100 Jason Smith

200 John Doe

300 Sanjay Gupta

400 Ashok Sharma

bonus文件中记录工号和工资

cat bonus.txt:

100 $5,000

200 $500

300 $3,000

400 $1,250

要求把两个文件合并并输出如下, 处理结果:

400 ashok sharma $1,250

100 jason smith  $5,000

200 john doe  $500

300 sanjay gupta  $3,000

这个应该是要求用shell来写的，但我的shell功底不怎么样，就用python来实现了

注意，按题目的意思，在输出文件中还需要按照姓名首字母来排序的

 #! /usr/bin/env python
 #coding=utf-8
 fp01 = open("bonus.txt", "r")
 a = []
 for line01 in fp01:
     a.append(line01)

 fp02 = open("employee.txt", "r")

 fc02 = sorted(fp02, key = lambda x:x.split()[1])

 for line02 in fc02:
     i = 0
     while line02.split()[0]!=a[i].split()[0]:
         i += 1
     print "%s %s %s %s" % (line02.split()[0], line02.split()[1], line02.split()[2], a[i].split()[1])

 fp01.close()
 fp02.close()
