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
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
#! /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()
python中合并两个文本文件并按照姓名首字母排序的例子
