标签:python,删除某行

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)
