什么是使用特定关键字从文本文件中过滤掉行的python代码？

Question

我的输入文件是包含以下链接的文本文件

usrls.txt

  

https://www.politico.eu/article/united-kingdom-brexit-eu-david-davis-the-uks-secret-brexit-strategy-so-stealth-even-the-british-cant-see-it/

     

https://www.reuters.com/article/us-britain-eu-scotland/scottish-independence-case-helped-by-brexit-chaos-sturgeon-idUSKBN1CD0B2

     

https://en.wikipedia.org/wiki/European_Union

     

https://en.wikipedia.org/wiki/EU_(disambiguation)

我想从此文件中过滤出Wikepedia的链接

预期输出

output.txt的

  

https://www.politico.eu/article/united-kingdom-brexit-eu-david-davis-the-uks-secret-brexit-strategy-so-stealth-even-the-british-cant-see-it/

     

https://www.reuters.com/article/us-britain-eu-scotland/scottish-independence-case-helped-by-brexit-chaos-sturgeon-idUSKBN1CD0B2

我尝试了下面的代码，但我没有输出。

from itertools import ifilter

with open('urls.txt','rb') as f,open('fliteredlinks.txt','wb') as g:

    g.writelines( ifilter(lambda line: 'wikepedia' in line, f))

Answer 1

for l in open("urls.txt").readlines():
    if not l.startswith("https://en.wikipedia.org") : print(l)

这会奏效。
