I saw a similar script on the homepage of Miguel Grinberg (the Flask book guy),
but he was using webscraping. Here I use simple API calls instead.

The script takes the presentations of a Python conference and orders the
presentations in descending order by the number of youtube views. It
is an indicator about the popularity of a video.

Usage:
    1) set the "conf" global variable
    2) launch the script

Requirements:
    pafy
    requests

Hi jabbalaci,
There was an error when I ran it.

Traceback (most recent call last):
File "pyvideo_popularity.py", line 28, in
from queue import Queue
ImportError: No module named queue

I think it should be "from Queue import Queue".

Thanks
Anshu
