Jupyter is also a python library. If you have Anaconda, then you have Jupyter installed already. If you do not have Anaconda (e.g. you started with a barebones Python installation), you can install Jupyter by typing
pip install jupyter
Then run it as follows:
jupyter notebook
It should open the browser with a list of files in the current directory. Create a new notebook, and there you go.
I tried it once and I just couldn't get used to it, but I may try again if my ide will not be up to task :-)
I strongly suggest you try again. At the moment Jupyter is the main tool for interactive data analysis in the Python community (and not only). Knowing your way around it is a must.
