Love the pace and the length of each lesson. It is very easy to understand, and also very interesting since he explains along with practical use cases. I feel more hopeful here in the middle of the lesson. Thank you!

By Idris Sumareh on 5/11/2026

The instructor is super clear and easy to follow. He really helps you get a solid grip on the fundamentals, like string manipulation and logic, in a way that actually makes sense. I love that I can take what I’m learning and immediately start building basic projects. Honestly amazing for anyone just starting out.

By Omowaye Joshua on 4/6/2026

building my technical skills. It provided a clear and structured introduction to key programming concepts such as data structures, control flow, file handling, and basic security practices. One of the most valuable aspects of the course was the hands-on exercises. They challenged me to think critically, debug errors, and apply concepts in practical scenarios rather than just memorizing theory. This helped me develop problem-solving skills and a deeper understanding of how programs work. I also found that the course aligns well with my interest in cybersecurity. Topics like password hashing, input validation, log analysis, and encryption gave me insight into real-world security practices and how software systems are protected. Overall, the course was a great fit for my learning goals, and it has strengthened my confidence in writing and understanding Python code.

By Alessandro Fioravanti on 12/6/2025

The course is well structured and great for beginners. The instructor explains concepts clearly and uses practical examples that make it easier to understand the logic behind the code. Some sections move a bit fast, but overall it provides a solid foundation for starting real Python projects. A good choice for anyone looking to begin coding in a simple and guided way.

By Ishaan Shukla on 6/21/2025

Love the course. Material explained clearly and understandably. Material is great and educational. Love the teaching style. Material is more understandable, especially for new people.

Let me just say that the instructor, Alexander, was good. I found him easy to understand and knowledgeable. I was hoping the course would be a little more hardcore cybersecurity, but it was nice that the examples were at least tailored in that direction. Unfortunately, I felt there were two issues that ruined the course for me. Firstly, I could hardly see what Alexander was typing on the screen as most of the time the video was zoomed out too far. I code on my laptop and watch the videos on my tablet and found it difficult to read. Secondly, there were very few coding exercises considering the volume of information and the verification tests didn't function correctly! I could literally write two lines of code that do nothing, hit 'Run Tests' and all the tests would pass. This makes it difficult to actually learn anything or verify that the code is working as it should be. Yes, I could run my code and tell myself if it worked correctly or not, but that kind of defeats the purpose I think. I liked Alexander as an instructor, but I think this course needs some improvements.

By Piotr Torba on 3/31/2025

The course is good however the author should zoom in his screen. It's hard to see it on 14" laptop screen. Besides that I liked the combination of different concepts eg. hashing function in the final project and encrypting library in one of other mini projects. I now edited my review and after finishing the course I give it 5*.

To name my first file I had to do one additional step which was missed in the lesson, maybe I'm working with a newer version

By Dick Jones on 12/26/2024

This is my first attempt to learn Python and I must say I am finding it quite easy due to the instructor's easy and calm approach. I am really looking forward to learning as much as I can from this amazing course.

By Kevin Smith on 11/14/2024

Really enjoying the course thus far. I am completely new to programming but the instructor takes his time to explain and I have been able to follow along. Really excited to see what kinds of programs I will be able to create soon.
