What are you more interested in learning, front end or back end development? Only asking since you mentioned Python and Bootstrap can be used/learned with server side rendered pages. My extremely general advice would be to avoid frameworks until you have a solid understanding of the fundamentals of both JS and HTML for front end stuff. This way you can understand what is happening behind the scenes with these tools. For back end Python is a great place to start. I would suggest learning some data structures (queue, stack, graph, binary search tree) and implementing them yourself along with some sorting algorithms (insertion, merge, quick, radix). That will give you a pretty decent exposure to the language. Try using Flask for a web framework as it's very simple on it's own and doesn't have as much magic as something like Django.
