I am listening to you well, teacher. Thanks to you, I am learning a lot. First of all, I can't implement it perfectly, or I just write the code and finish it, and I feel refreshed when I listen to the teacher's lecture and hear the answer. When I try to do it with Visual Studio Code on my MacBook, it is a little different from doing it on Windows, so I started by studying how to read text files, and now I am following along without any problems. I want to finish Python quickly and review it again, and study the C language test. And I think I will eventually study Java, so is there any chance that a Java lecture will be uploaded?
