Python - getting started

I’m doing some python online intro courses, and although most provide a browser console where I can input my code, I need to figure out the best way to test things out on my own computer as well.
I am getting to Numpy, and have no idea where/how to install it on my actual python on my computer. For playing around and exercising code, should I use Python (so the Python 3.8 console on my windows), the Jupyter QtConsole that I can access through Anaconda, or something else?
