[trx_accordion_item title=”Introduction”]The CodingEntrepreneurs have an excellent online Udemy course “Coding for Entrepreneurs: Learn Python, Django, and More.” Obviously to take the course you need to install Django. To that end, they have a great Youtube video.

Starting/stopping the video as I follow along is great, but I prefer to also have notes in outline format. Notes help me understand learning objectives and serve as a review after I’ve completed the lesson.

This post provides companion notes to their Youtube.
