Even in 2021, when Python is all the rage, it is still the best in the military. It is said that there is no other lecture that can compare to “Jinseok Lee’s Janggo” in Korea or abroad. I think it was around 2017? When I first started learning Python, I first encountered Jinseok’s lecture (on another site). I learned the basics of Python grammar on my own and had no understanding of the web, so there were a lot of holes. Jinseok’s lecture was a great help not only in learning Danggo, but also in learning the basics of Python and programming. Thanks to this, I have experience in creating and operating a blog myself, even though I am not a professional developer, and I have also done a very successful side job creating simple web pages. Many people recommended or introduced me, so I earned dozens of times the monthly tuition fee without having to do any separate platform, advertising, or promotion. (In my case, I was lucky enough to be able to work on temporary local festivals, ㅇㅇ Festival, or ㅇㅇ Contest webpages produced and operated by local governments or small and medium-sized event companies. The framework is generally similar and the production difficulty is easy, so it's good to try.) Compared to that time, there were many additional curriculums such as React, Instagram tutorials, and AWS in Jinseok's lectures, but I would like to give him a big score for the fact that this lecture was not created in a day or two like roasting beans in a flash. It's a lecture that tastes like well-cooked fermented soybean paste or fermented soybean paste. It's well-polished, so there's no excessive or insufficient part. (Of course, it might be different for current web developers, but for beginners to intermediate level, I think this one is enough.) When my colleagues or acquaintances ask me to recommend Python web development, I never mention another lecture. I only recommend "Infraun's Lee Jinseok." I wonder if there are other lectures that are this good. And I've searched other sites many times, (of course there were some good lectures) but I don't think there was a lecture as good as this one. I want to recommend this lecture more strongly, but I guess my writing skills are limited to this pointㅜ I'll stop here. In conclusion, since it's an unlimited course for life, I recommend that you take it at least once in your life so that you can refer to it when you need it. Have a happy day!
