Being new to python web-scraping, this code seemed pretty helpful.

thanks

I'm working on my first html scraper, your article was very helpful, thx! :)

Thanks, Very Helpful 😄

many thanks for helping me.

i received error while executing it
8\lib\support\dbgp\python3lib\dbgp\client.py", line 675, in init
exec(contents, globals, locals)
File "", line 12
response = requests.get(index_url)
^
IndentationError: expected an indented block

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.

Thanks! Tremendously helpful!

This awesome snippet help me better understand in tutorial in python programming.
Thanks

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')
