I find REPLs and IDEs a great way for learning the libraries and APIs by exploration.

Install iPython (the command line, not the notebook interface. The CLI is simpler). Install the libraries you will work with in your new software stack. Read the manuals, do the "hello worlds". Then type some variable and a question mark afterwords. This will show the documentation. Two question marks show the actual code of a particular function in question. This is great for digging around in the libraries. Many IDEs such as PyCharm have similar options when you have code and can navigate all the way down the rabbit hole in the libraries.

For many libraries in python, this attemp is not so useful. For instance, numpy delegates much work to actual C code and a lot of magic is involved.

Generally, Python has rather few specific syntax, compared to other languages. The language is rather small and you will spend more time on the libraries then on learning the actual language.
