刮youtube播放列表

我一直在試圖寫一個python腳本，它將獲取我的歌曲名稱中包含的鏈接將被提供的播放列表。例如。 https://www.youtube.com/watch?v=foE1mO2yM04&list=RDGMEMYH9CUrFO7CfLJpaD7UR85wVMfoE1mO2yM04從終端。刮youtube播放列表

我發現使用「li」標籤或「h4」標籤可以提取名稱。我寫了下面的代碼，

import sys 

link = sys.argv[1] 


from bs4 import BeautifulSoup 
import requests 

req = requests.get(link) 

try: 
    req.raise_for_status() 
except Exception as exc: 
    print('There was a problem:',exc) 

soup = BeautifulSoup(req.text,"html.parser")

然後我試圖使用鋰標籤作爲：

i=soup.findAll('li') 
print(type(i)) 
for o in i: 
    print(o.get('data-video-title'))

但它印有「無」的時候那些數字。我相信它無法達到那些包含data-video-title屬性的li標籤。
然後我試圖採用div和H4標記爲，

for i in soup.findAll('div', attrs={'class':'playlist-video-description'}): 
    o = i.find('h4') 
    print(o.text)

但沒有再次發生..

玉傢伙，我已經想通了什麼正在發生。我的代碼是完美的，它的工作正常，問題是我從終端傳遞鏈接作爲參數，並且偶然地，鏈接包含一些符號，這些符號以其他方式被解釋爲例如。（'&'）。現在我通過鏈接作爲字符串在終端，一切正常。如此愚蠢又費時的錯誤。

h4 = soup.find_all("h4")
