For some reason python is giving me zero data from the request made. Could there be an error in the request

error has been fixed:
The html page doesn't have the video-summary-data div class anymore, so I just used the row div class.

I was also having an issue with the get_video_page_urls() method not being able to retrieve any urls. I changed video-summary-data to row and now it looks like it's working.

This is how the updated version of the Soup should look like:

in get_video_page_urls():
soup.select("article > a[href^='/pycon']")]

in get_video_data():
video_data['title'] = soup.select(".entry-title")[0].get_text().replace("\n", "").strip()
video_data['speakers'] = soup.select(".author a")[0].get_text()
video_data['youtube_url'] = soup.select(".details-content li:nth-of-type(3) a")[0].get('href')
