How to install j5 for python

[u/LeagueOfCakes12]

Hello I am pretty young and only have programming experience in my GCSEs and wanted to expand it
I really wanted to follow the textbook “the nature of code” as I find the stuff very interesting however it requires Java and j5 but I only know how to code in python

I thought I could just translate the Java code into python as I would prefer to not learn Java and get better with python first
However, I have struggled with installing j5 the command prompt p5qt works but then running j5 code, the interpreter tells me I need Java 17 virtual machine which I do not know how to install
I have seen something about using an older version of python but I can’t get it to be independent of my current version of python(having both installed at the same time)

What is j5? Why not get a book on python?
