title: Download Youtube subtitles without timer using pytube
body: <p>I am using pytube to download subtitles of youtube video. I want to download them without time information. I have checked their API documentation but I am unable to find option to get subtitle without timer. Following is my code.</p>
  <pre><code>from pytube import YouTube
  source = YouTube('https://www.youtube.com/watch?v=6Af6b_wyiwI')
  en_caption = source.captions.get_by_language_code('en')
  en_caption_convert_to_srt =(en_caption.generate_srt_captions())
  print(en_caption_convert_to_srt)
  </code></pre>
