I put it in my shopping cart and thought I should listen to it someday, but I'm listening to it now, but really... I think a lot about whether my Python wandering would have been a little shorter if I had listened to it earlier... I also think a lot about whether I could have listened to this lecture while absorbing it this much if I had listened to it then. If I had listened to it without Python wandering, I think I would have just listened to the lecture like watching Uncle Bob explain the pictures. When I was learning, there was no class in the curriculum itself for Python basics.. This year, while I was wandering around Python, I couldn't find a book that would help me grasp the concepts related to classes. Still, I tried to force myself by copying and pasting from blogs, stackoverflow, and github.. But since I didn't have the basic concepts, I ran into limitations. Honestly, most of the books I found for classes only covered the level 1 of the instructor's Python lectures. But that knowledge alone has its limits. I can write good code with just level 1 class knowledge, but when I tried to go further, stackoverflow wasn't helpful, so I ended up reading the official documentation. But the official documentation... is not friendly, as it thinks I already know everything to some extent. I wandered around feeling a sense of disconnect there, but every time I listen to the lecture, I understand the codes that I either wrote thinking it was like that because I didn't understand them, or gave up because I got an error. I really felt like I could now be a Python developer since yesterday, but in today's lecture, the instructor also said this ㅋㅋㅋㅋㅋㅋㅋ I don't know if I should be this confident, but right now, I've only done data analysis work rather than developer work, and I've only developed various things with Python, but I want to say I'm a developer. Now, I'm not scared of the codes on github. I don't have to just pass over them thinking, "What is this?" Thank you for the really great lecture ㅠㅠㅠ Really.. I feel like something is lacking, but I don't know what it is, so I can't search for it, and if I search for something, I don't even know what it's talking about.. If it's in the class-related code, listen to everything from lv1. I applied for lv2 after reading a review that said it would be good to do lv3 before lv2, and I listened to lv1 and lv3 after listening to lv2. In my opinion, the class-related content is expanded appropriately to lv1, lv2, and lv3. The lecture has class content, but it's not just a class. I was wandering around in class for so long that I'm so touched by the class.
