這是正則表達式代碼：without_header = re.findall('/sports/[a-z0-9\/\.\-\:]*[0-9\.]+cms', without_header_url)它返回每個 URL 的輸出，該 URL 前面沒有 https 標頭。例如：/sports/cricket/ipl/top-stories/kxip-vs-csk-shane-watson-faf-du-plessis-infuse-life-into-csks-ipl-campaign-shape-confidence-boosting-win-over-kxip/articleshow/78481088.cms' /sports/football/epl/top-stories/epl-manchester-united-humiliated-as-mourinhos-spurs-win-6-1-at-old-trafford/articleshow/78481304.cms為此，我想在開頭附加“https://example.com”。我不需要 for 循環，有沒有使用 re.sub 的有效方法？
