Bookmarked your Python link! (Welcome back by the way.) I have had multiple goes at teaching myself some web frameworks but have frustratedly quit almost every time. Last web project I just resorted to HTML/CSS with only the bare minimum JS/jQuery, outsourcing the hosting to Github Pages. But then again I wouldn't call myself good at any of those things.
I was where you are a few months ago. I recommend playing around with Digital Ocean droplets to understand web servers, they make it very easy (and their documentation is excellent). With nginx you can have a static site up in <15 min. I have a peripatetic posting style....Let me know if you have any questions about web frameworks, I had several conversations with friends that led to eureka moments.
