业务需求
需要将文本文件分每两行一组
jb51.txt
1:www.jb51.net
2:www.jb51.net
3:www.jb51.net
4:www.jb51.net
5:www.jb51.net
6:www.jb51.net
7:www.jb51.net
8:www.jb51.net
9:www.jb51.net
10:www.jb51.net
11:www.jb51.net
12:www.jb51.net
13:www.jb51.net
14:www.jb51.net
15:www.jb51.net
16:www.jb51.net
核心代码：
# -*- coding: utf-8 -*- ''' python读取文件，每两行为一组 ''' def fenhang(infile,outfile): infopen = open(infile,'r',encoding='utf-8') outopen = open(outfile,'w',encoding='utf-8') lines = infopen.readlines() i = 1 for line in lines: if i % 2 == 0: outopen.write(line+'\n') else: outopen.write(line) i += 1 infopen.close() outopen.close() fenhang("jb51.txt","o.txt")
通过执行 python jb51.txt
o.txt的内容
