As a JS dev learning python should be trivial. As language python is much easier. The main issue is it lacks many libraries that you are used to working with in the js world - but thats because python isnt really a web language.

All in all learning the basics should take no longer than two to three weeks, despite lower quality documentation.

One way to do it may be to pick one of the many useful node libraries and implementing them in python.
