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("jb51.txt","oushu.txt","jishu.txt")

效果图

python奇偶行分开存储实现代码

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。
