Hello, Nadocoding. I got to know you through your Python lectures on YouTube. Learning Python was really fun. The concept of concretizing and realizing what was in my head through a program was really fun. Actually, I worked in distribution and loading and unloading couriers for several years, and then I first encountered the language called Python.... But I decided to quit my job a year after I encountered the language... I'm 30 years old, but I was so amazed that this field was so interesting and that the concept of studying fit me so well. I'm taking Java lectures in advance before entering a government-funded academy, but as expected, you're training me with a more solid curriculum than when I was learning Python :) It's scary to start at such a late age, but I think I'll be able to accept any situation and any appearance if I jump in and break and shatter rather than regret not doing it. I talked a lot because the future was dark... ㅋㅋㅋ Nadocoding, you're really helping me a lot. Thank you so much.
