That said, most things won't have a go-to selection of screencasts. Ruby on rails is the exception with railscasts.
There are some good knock-offs in other languages/stacks, but they're by no means ubiquitous.
Here's some screencasts, and it's easy to google for more, or search youtube: http://neckbeardrepublic.com/screencasts/
You will also find the Django tutorial very nice, and djangobook: https://docs.djangoproject.com/en/1.7/ http://www.djangobook.com/en/2.0/index.html
Note that the djangobook is somewhat outdated, though most of it still applies. You just might need to look up new syntax once in a while, all the ideas are pretty much the same.
