下面小编就为大家带来一篇Python 实现简单的shell sed替换功能(实例讲解)。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧
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!
