[20.12.21] I have currently listened to the latter half of the first unit. First of all, since the lecture topic is 'using Python', those who have listened to the preview will know that it only briefly touches on the basics of Python and does not cover them in detail. Rather than those who know nothing and want to study the basics, I think it is better for those who already have basic knowledge of Python or other languages (C, C++, etc.). Of course, since the topic is the topic, those who have basic knowledge will look for it and listen, but I am leaving it here just in case. If you are a complete beginner and want to learn the basics of Python in detail, I recommend taking a lecture that consists entirely of beginner-level Python content! I have only listened to the very beginning, but so far, I have felt that the instructor has really picked out the core parts and explained them concisely. However, since it is so concise and only covers the essential parts, I am worried whether I will be able to follow the lecture smoothly when I move on to the subsequent content. I studied C/C++ and recently started studying Python. When I was studying C, I only skimmed over the TCP/IP part (just following the examples in the book?), and I am completely ignorant of security. I chose this lecture because of the lecture topic, 'IT Hacking and Security Using Python', and I will gradually revise the review as I continue to listen to the lecture. I hope this will be of some help to those who are considering this lecture😊
