@ShrutiVPawaskar This looks good, but I have one piece of important feedback. I'd like this to be split up into two lessons. Let's build a lesson totally focused on Jinja2, using the simplest possible software to illustrate examples. I'm thinking a little bit of YAML and Python to populate the templates, but the templates should be the focus. I'm thinking this would be a fundamentals lesson.

Separately from this, I'd like to see a lesson totally focused on PyEZ. It deserves its own lesson anyways, and putting it into the configuration course probably makes more sense at the moment.

Feel free to create a separate issue for the latter and write in the description that you're working on that as well.

@Mierdin we have simplified the jinja2 lesson to make it fundamental and focus more on jinja2 templating. The lessons are as below:

• Part 1: Intro to Jinja2 (variable substitution)
• Part 2 : For Loops in Jinja2
• Part 3: If and Set statements in Jinja2
• Part 4: Populating Jinja2 template with YAML
