帶有多個“.”的 Python requests.get() url

Question

我正在編寫一個腳本來抓取網站並下載當前的 mp3 文件，它使用帶有Python 3.6.3 BeautifulSoup將以下所有鏈接抓取到各個藝術家頁面中，但一些抓取的 URL 包含多個“.”。 當我開火時

request.get(url, header=<random header using fake_useragent>)

它不會下載文件，我該如何更正？

例如：

URL > abc.com/mp3/artist/songs/song.com.mp3 (not downloading)
URL > abc.com/mp3/artist/songs/song.mp3 (downloading) 

代碼 ：

def download_mp3(url_list_file, download_dir):                                                                                                                                                                   
    with open(url_list_file, 'r', encoding='utf-8') as urls:

Answer 1

得到它更正替換所有“。” 在 URL 中，除了最后一個使用百分比編碼的“.mp3”

string.replace('.', "%2E", (string.count('.')-1))
