作者:Bigberg

下面小编就为大家带来一篇python 文件操作删除某行的实例。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

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)
