I think this is the best lecture series for those who study alone. It wasn't easy to learn backend technology on my own, but after watching this lecture, I felt like I was reading the 'flask standard'. It's an oasis-like lecture with a mentoring-like feel, detailed explanations, focus on understanding, and abundant materials. If you think of time as money, It's much more cost-effective to learn this lecture and learn additionally than to struggle and learn alone from the beginning. At the beginning of this year, I started with the instructor's introduction to Python with a light heart. It was a year when I felt that I could make something with my own hands by listening to all the lectures step by step. Now, I'm thinking that I want to develop seriously. ㅎㅎㅎ This flask lecture is also difficult for me, but I'll absorb it quickly and make it mine. Thank you this year and I'll thank you in advance next year!
