The book ‘Python Multiprocessing Jump-Start’ was easy to understand, even though I knew nothing about multiprocessing in Python. The text was easy to read and the program examples, which were crystal clear, worked without problems to run in my Visual Studio CODE on Windows 10 and Python 3.10.4 (except for ‘fork’, which doesn’t work on Windows) Before I was half way through the book I had written a multitasking Python program that immediately went live, with one user. (which reduced his wait time from 40 minutes to 10 minutes, on each use). 4 times faster! (using 5 cores, on a 6 core processor)
