This is a book on how to code in Python. Of course the title is a bit of exaggeration. The “hard way” is learning by doing, not by reading. The author would ask you to manually do every simple command, and type (not copy-paste) every line of code. If you really want to learn Python, as opposed to “dabble” in it, then this is a recommended book. It is totally free.
(I wanted to put a picture of a python — the reptile — with this entry. But when I did Google Image Search, I got so many snakes all over my computer screen. I cringed and closed the tab promptly).
