Hỏi về Regex trong Python

Kulteam · January 10, 2022, 6:09am

Tình hình là hum rồi mình có lượn vô Deepweb tải vớ vẩn mà tải từng file một nó lâu quá nên viết một script đơn giản với mã nguồn copy và paste mỗi chỗ một tý.Mình có một vấn đề đối với việc lấy danh sách link torrent bằng regex như sau

import re
list_link=['https://abc.com/file1.torrent','https://abc.com/file2.torrent','magnet:?xt=urn:btih:69d157a3137e1fa3b62e14f6ece8621ff4aadd64','magnet:?xt=urn:btih:659f4ee96c7a76e89c9c44297d260c9680445e88&dn=%2B%2B%2B%20MDB-988%20%E3%81%A4%E3%82%8B%E3%81%A4%E3%82%8B%E3%82%AA%E3%83%9E%E2%97%8F%E3%82%B3%E3%81%AB%E3%81%BA%E3%81%9F%E3%82%93%E3%81%93%E3%82%AA%E3%83%83%E3%83%91%E3%82%A4%E3%81%AE%E7%BE%8E%E5%B0%91%E5%A5%B3%E9%81%94%E3%81%8C%E5%A4%A7%E9%9B%86%E5%90%88%EF%BC%81%EF%BC%81%E8%B2%A7%E4%B9%B3%E3%83%91%E3%82%A4%E3%83%91%E3%83%B3BEST30%E4%BA%BA4%E6%99%82%E9%96%93&tr=http%3A%2F%2Fsukebei.tracker.wf%3A8888%2Fannounce&tr=udp%3A%2F%2Fopen.stealth.si%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969%2Fannounce&tr=udp%3A%2F%2Fexodus.desync.com%3A6969%2Fannounce']
regex="magnet:\?xt=urn:btih:[a-zA-Z0-9]*|.torrent$"
r=re.compile(regex)
list_link_torrent = list(filter(r.match,list_link))
print(list_link_torrent)

Và đây là kết quả:

['magnet:?xt=urn:btih:69d157a3137e1fa3b62e14f6ece8621ff4aadd64', 'magnet:?xt=urn:btih:659f4ee96c7a76e89c9c44297d260c9680445e88&dn=%2B%2B%2B%20MDB-988%20%E3%81%A4%E3%82%8B%E3%81%A4%E3%82%8B%E3%82%AA%E3%83%9E%E2%97%8F%E3%82%B3%E3%81%AB%E3%81%BA%E3%81%9F%E3%82%93%E3%81%93%E3%82%AA%E3%83%83%E3%83%91%E3%82%A4%E3%81%AE%E7%BE%8E%E5%B0%91%E5%A5%B3%E9%81%94%E3%81%8C%E5%A4%A7%E9%9B%86%E5%90%88%EF%BC%81%EF%BC%81%E8%B2%A7%E4%B9%B3%E3%83%91%E3%82%A4%E3%83%91%E3%83%B3BEST30%E4%BA%BA4%E6%99%82%E9%96%93&tr=http%3A%2F%2Fsukebei.tracker.wf%3A8888%2Fannounce&tr=udp%3A%2F%2Fopen.stealth.si%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969%2Fannounce&tr=udp%3A%2F%2Fexodus.desync.com%3A6969%2Fannounce']

for link in links:
