I got to know Qt through a project, I ran GPT by force, and used it without knowing the functions and implementation principles, and then I accidentally found a lecture like a rain in the desert and paid for it right away. It's a really good program if you use it well.... There was no one to teach me how to use it, no lectures, and no books, so it was really frustrating. If you want to create a GUI based on Python in your own way, and if you want to separate the function module and designer module for maintenance after you become a little more skilled, I recommend taking Level 2. Actually, I'm taking Level 1 after watching Level 2, I searched to find out the basic content, but there are few Qt-related videos, and the ones that are available are very old, so I wonder if the code will work as the video says. I also looked for related books, but the books that came out were either in English or not at an entry level. I think this lecture is the only(?) updated Qt lecture. They say that electronic devices and delivery food are something you're going to buy anyway, so it's just a matter of time, but I want to put this lecture series next to electronic devices and delivery food as a matter of time 😊😊 I would like to thank the instructor for preparing the lecture with all his heart, and I hope all the students will study hard and get good results!
