My first scraping tutorial

Thanks for the tutorial, just to mention that the DOM of the html is changed and some portion of the code needs to be modified.

DOM has changed kindly edit this script so some thing newbee like me also learn something.
Pl. put light on Selenium-Python 3.5 also
thanks in advance.

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')
