前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
代码如下:
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
代码如下:
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:
代码如下:
400 ashok sharma $1,250
100 jason smith $5,000
200 john doe $500
300 sanjay gupta $3,000
这个是要求用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,实现代码
代码如下:
#! /usr/bin/env python#coding=utf-8fp01 = 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()
