code:
f = open('yesterday','r',encoding='utf-8') f2 = open('yesterday.bak','w',encoding='utf-8') old_str = input('请输入要修改的字符:') replace_str = input('请输入替换成的字符:') for line in f.readlines(): line = line.replace(old_str,replace_str) print(line) f2.write(line) f.close() f2.close()
文件内容:(yesterday)
Somehow, it seems the love I knew was always the most destructive kind 不知为何,我经历的爱情总是最具毁灭性的的那种 Yesterday when I was young 昨日当我年少轻狂 The taste of life was sweet 生命的滋味是甜的 As rain upon my tongue 就如舌尖上的雨露
感想:
思路很简单就是打开源文件,然后循环,把源文件要替换的内容替换再写入新文件!
以上这篇Python 实现简单的shell sed替换功能(实例讲解)就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。
