Great read for students
Format: Paperback
Studying cybersecurity, I thought "Black Hat Python, 2nd Edition" by Justin Seitz and Tim Arnold was quite helpful. This book makes difficult ideas far simpler by combining theory with practical examples. The revised material maintains it current given the cybersecurity issues of today. The practical uses it goes over, such as scraping and sniffing, which are essential skills for anyone working in the field. Whether you're brand-new or seasoned, the simple explanations make it easy to follow. Any student studying cybersecurity should not miss this book since it provides the ideal combination of knowledge and useful abilities through guided projects.

The book is simply perfect. Very good book. Problem with shipping.
Format: Paperback
The book is simply perfect. Good book and good practical contents, complex, but direct at the same time with what it has to say. Very useful if you want to learn Python but from the point of view of a Hacker or Pentester.
There was a problem with the shipping, it was solved, but I received the book days later and for a few hours the book was lost, and the shipping agency couldn't track it, and they didn't know where it was. Luckily in the end it was fixed and I received it a few days later.

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!
