我是靠谱客的博主高兴黑裤，最近开发中收集的这篇文章主要介绍python 文件操作删除某行的实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

使用continue跳过本次写循环就可以了

#文本内容
Yesterday when I was young
昨日当我年少轻狂
The tasting of life was sweet
生命的滋味是甜的
As rain upon my tongue
tasting
I lived by night and shunned the naked light of day
tasting123
And only now I see how the time ran away
tasting
 
tasting

将文本中的 tasting123删除　

with open("fileread.txt","r",encoding="utf-8") as f:
 lines = f.readlines()
 #print(lines)
with open("fileread.txt","w",encoding="utf-8") as f_w:
 for line in lines:
  if "tasting123" in line:
   continue
  f_w.write(line)

以上这篇python 文件操作删除某行的实例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。
