http://pyvideo.org a site for videos on python
http://pyvideo.org/pages/about says that
This is a video index of Python-related video on the Internet. It does
not host video—it’s an index.
Each video is lovingly packaged with a variety of metadata that
comprises the context of the video: When was it taken? What was the
venus? Who was speaking? What was the topic of the talk? What are the
related links? Are there quality issues with the video?
Nice initiative to get all the python videos in a single place.
