*The review below is a review left for a lecture on the YouTube channel operated by Nadocoding.
This is a great lecture!! It is organized step by step well considering the beginner's perspective.
Not only is the content optimized, but the instructor's delivery skills are top-notch .
Thank you. Thanks to you, the programming that I had been wandering around for a long time has been completely organized in my head. I feel like the world has become bigger . I am working on a project to make audiobook production extremely efficient with AI, and I think it will be successful :-) Thank you!
I'm leaving a comment because I'm so grateful. I've tried many free and paid courses, but I gave up on them all. I need to study machine learning, so I urgently needed a basic Python course. I'm almost done with the basic Nado Coding course. It's really a new world. It's much better than expensive paid courses. I also really like how you use real-life examples.😊😊 I look forward to data analysis and machine learning in the future! Thank you so much!
I really didn't know how to do it, so I just let it go, but after watching this lecture, it's so well-received in my head that I can say it out loud and write it down with my hands..! Thank you, teacher. This is truly a national treasure lecture 😭
It says that I started programming 10 months ago with this video. I have been working as a Java developer at a pretty good solution company for about a month now. I started studying with half-heartedness, but thanks to this video, I was able to learn programming really quickly and easily. I was able to catch your interest . Thank you so much for making such a great video. I hope that everyone who studies while watching this video will achieve their goals!
I can confidently say that this lecture changed my life . I didn't know what code was, what data types were, or what lists were. But with just this video, I was able to pass the pre-exam for the national data course. And I'm grateful for more than a day or two of thinking about how I could have written code in Python if I hadn't taken this lecture while taking the current course! Beginners, don't be afraid. If you listen diligently for a week, you too can become a Python user.
I'm a 42 year old babycoder from Paris.. All the things I was curious about since I fled were explained in detail and kindly, so I understood everything 😢😢 I've never coded before.. Even when my friends explained it to me, I didn't know what they were talking about, but now I understand everything 😭😭 Thank you so much 😭😭 I'll come often!
This person's lectures are truly a donation of talent. He explains difficult things very smoothly . He is a genius at teaching.
"I also enjoyed this lecture. I now want to try getting stock information that interests me and processing it into graphics.
When I think about why people who have taken this course rave about it , I think that most of the books and lecture seminars we learn from only teach us successful results, but this course teaches in a way that gives us the feeling of growing together while making mistakes, the confidence that we can do it, and additionally, asking us to try something on our own to learn more deeply. It is a great course that makes us think about many things in many ways, not just the content of the course^^"
These days, I've been watching and following Nadocoding's lectures all day and time is flying by 😊😊 This is already the last lecture on Python!!! I can't wait for the next ones 😊😊 Originally, I should be happy when there are no more lectures left, but the lectures are so good that I'm sad 😊 I'll finish this episode well too! Thank you always for the great lectures!!!!!!!!! Fighting ୧ʕ•̀ᴥ•́ʔ୨
Hello. It was a long lecture of over 9 hours , but it was not boring at all, and it was fun to learn little by little . It was a meaningful time because I was able to use various modules and functions and think of ideas that can be applied to real work. I look forward to the next lecture. Thank you very much.
At the age of 30, I have been working as a freelancer all my life, and by chance, I have come this far from the basics of Python. Thanks to your diligent teaching, I have been transferred from the HR team to the development team and am living happily . I would like to meet you and say hello, but I am sorry that I cannot, and I am so grateful. Thank you for guiding my life.

(Advantages) 1. Even non-majors can learn Java in a short period of time 2. Interfaces, lambda expressions, and streams are explained very easily. (Disadvantages) 1. Since the lecture time is short, I have to find a separate book to study detailed contents such as classes, inheritance, polymorphism, and interfaces. --> Honestly, I think it is natural because the lecture time is short. --> It would be perfect if it was supplemented with detailed contents in a PDF file, but the cost is too cheap, so I think it is too unscrupulous. (Conclusion) I have listened to the basics, so I would appreciate it if you could give me an advanced version.

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.

Full-time Nado Coding's Java course It was a lecture with a clean progression, appropriate lecture length, and a powerful voice. The explanations after the class part were surprisingly easy to understand. I can see traces of a lot of preparation. I received a lot of help from the Python lecture, and now Java is also helping me like this. I will work even harder. Thank you, instructor. Thank you for your hard work.
Hello, bigcat0815 You completed the long lecture really quickly 🎉 I thought a lot about making easy examples and code structures because the class might be difficult for beginners, but I'm so happy that you said it was easy to understand 😭 Thank you so much for your valuable review 🙏 I hope the content you learned this time will be helpful for places where Java is needed. Have a warm year-end and a happy new year! Thank you 😊 - I also code

Hello. I am a late bloomer who applied for a boot camp and then dropped out and is studying on my own!! First of all, if you are a non-major like me and are learning Java for the first time, you may think that the lecture content is somewhat lacking. In my case, I read 'Java Essentials' once and took this lecture. I think I understood and learned more than 90% easily. Of course, it is also thanks to Nako-nim's powerful teaching skills!! Must-reads -> Nako Java (dessert after the main dish) Nako Java -> Must-reads (main dish after the appetizer) I think you can choose according to your taste!! Thank you, Coding-nim : )
Hello, Yuntoben! It is not easy to study a programming language on your own without anyone's help as a non-major. In particular, it requires a lot of will and effort to read a thick book like 'Java's Essentials' instead of an online lecture. 👏 I think Yuntoben already has enough perseverance and concentration since you read it once. Compared to a book that is almost 1,000 pages long📚, 20 hours of basic lectures👨🏫 may feel a little lacking. Since it is a basic course, I boldly excluded parts that suddenly increase in difficulty or that beginners do not need to know. I think it is more important to learn the overall content and complete it from the beginning to the end at least once rather than studying every topic in detail and giving up in the middle. That way 💪 you can gain confidence and get a feel for what programming is like 😁 I think it's a really good study method to study like you're studying now, whether you first read the book and then review the lecture, or study the content through the lecture and then reinforce it with the book. Your analogy is good 😲 I sincerely thank you for taking the class, and I sincerely hope that you will master Java through this opportunity and get a job where you want 🙌 Thank you. - I also code
