I went to about 3 computer academies in Gangnam offline, took classes on a site with a similar name to Post-it, and read about 6-7 books on Python. Maybe it's because I'm not a major, or because my job isn't development-related (I work in the CS industry), but I often felt like my skills weren't improving even after spending so much time. During that time, I came across a course called "Introduction to Python and Creating Various Automation Applications Using Web Crawling" on Inflearn, and my perspective on Python changed. I created and distributed a work automation application for my current company and received an award, and based on what I learned from a good person, I successfully transferred to a large company by writing my resume. I hesitated a lot about whether or not to buy the beginner's course. When I looked at the table of contents, I thought that most of the content was already familiar, so I wondered if it was really necessary to listen to it, but I bought it out of loyalty to the good person and Inflearn. (I intentionally waited for the discount to end before buying it...) In the end, I made the right purchase. I was able to review the content I already knew, and I learned about 4~5 things I didn't know. It was a lecture worth the money. I really liked that it covered the basics solidly, and I think it's probably the only lecture in Korea that tells you how it can be used in future development work. I'm going to take the intermediate course now!
