Django (2.0): An Introduction for Beginners

description
Learn Django in this video by following along as I show you how to build a simple hello world app and then a guestbook app that uses the templates, models, and form functionality with Django. Django is a huge library, so this video doesn't cover everything, but if you're new to Django or want to see how Django v2.0 is different, check this video out. Need one-on-one help with your project? I can help through my coaching program.
