I first learned about it through 'Non-major but I make a living as a developer'. I am also a non-major among non-majors who study completely different things and work in different fields. I enrolled in the AI convergence education master's program and took classes, and became interested in big data analysis, so I ended up getting ADsP and big data analysis engineer certifications. And in the process, I received a lot of help from the Naver cafe called Data Expert Forum. Then one day, I saw a book review of 'Non-major but I make a living as a developer'. I bought it just by looking at the title. Haha. Actually, I was also thinking about changing jobs. The information was useful, but the writing style was so interesting. I learned about this course from Inflearn through that book, and I paid for it without hesitation. In fact, I had already covered some basic Python grammar and libraries in my graduate school classes, so it was good to be able to listen to it lightly as if I was reviewing it. Above all, this course was good because it was conducted in a thick and bold way (for example, acfhilm....) rather than the traditional abcd.... I learned a lot of practical ideas that I could use right away. In terms of cost-effectiveness, this is the best Python course in Korea. As the title suggests, it is a course that perfectly suits the sensibilities of Koreans. Along with paying for the course, I also bought three more books written by the instructor. (Coding Public Interest, HTML+CSS+JavaScript that Creates Webpages Just by Coding, and Work Automation that Finishes 6 Months' Work in One Day) Unlike existing IT books, these books are soft and friendly, and have a 'humanistic sensibility' that is perfect for me. I look forward to the instructor's (developer, writer) continued activities, as he blew away the stereotype that science students are stiff.
