我正在尝试根据某些（或一组）关键字抓取YouTube视频。到目前为止，我只能下载YouTube视频的首页-大约20-30个视频。到目前为止，我已经使用BeautifulSoup，urllib.request和pytube进行了必要的操作。我在此处附加了一些代码：如何下载更多/所有与特定关键字相关的视频？

 # Search through divs 
    for i in divs:
        href= i.find('a',href=True)
        urls.append([href.text,"https://www.youtube.com"+href['href']])
        video_details = {}
        hashtags = []
        for link in divs:
            for span in link.findAll('span',attrs = {'class':'standalone-collection-badge-renderer-text'}):
                for a in link.findAll('a',attrs={'class': 'yt-uix-sessionlink'}):
                    hashtags.append(a.text.strip())
                    video_details['HASH_TAGS'] = hashtags
        #print(hashtags)

def Downloader(url):
    yt = pytube.YouTube(url)
    video = yt.streams.first()
    video.download('x')
