python奇偶行分开存储实现代码

例子：

1:3water.com
2:3water.com
3:3water.com
4:3water.com
5:3water.com
6:3water.com
7:3water.com
8:3water.com
9:3water.com
10:3water.com
11:3water.com
12:3water.com
13:3water.com
14:3water.com
15:3water.com
16:3water.com

python函数代码

# -*- coding: utf-8 -*-
'''
python读取文件，偶数行输出一个文件，奇数行输出一个文件
'''
def fenhang(infile,outfile,outfile1):

 infopen = open(infile,'r',encoding='utf-8')
 outopen = open(outfile,'w',encoding='utf-8')
 outopen1 = open(outfile1, 'w', encoding='utf-8')
 lines = infopen.readlines()
 i = 0
 for line in lines:
 i += 1
 if i % 2 == 0:
  outopen.write(line)
 else:
  outopen1.write(line)
 infopen.close()
 outopen.close()
fenhang("3water.txt","oushu.txt","jishu.txt")

效果图

python中%代表什么意思

求模运算，相当于mod，也就是计算除法的余数，比如5%3就得到2。
