- #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)
