Tough read for a newbie
Format: Paperback
To start off, I am not the world’s best at writing code. I do have a low level understanding of the concepts and can figure out (with a longer amount of time) how to get some of the code functional.
With this in mind, this book (if your a beginner or struggle with Python) is going to be a tough read and hard to practice. Its pseudocode is solid and makes the coding easier but you need to beware of pythons syntax differences between the different versions when you are using this. (This is something I struggle with).
I am beyond happy with this book, albeit there are typos and errors inside it but I think it’s solid for practice in this field.
Coming from a nontechnical profession, having the concepts explained and taken out from theory into working practice helps understand the practical side of doing something like this.
Despite being a tough read, i have the frame of mind that ethical hacking and program development is not for a total newbie and some experience is needed for maximum efficiency.
Hope this helps!
