Hello Taeho Park, Thank you for taking the course 😊 It's great to hear that you are following along by typing the code yourself—that is the best way to learn! I'm glad to hear that you are finding it easy to understand, even though this is your first time using Python after working with other languages. Python has a very concise syntax, so once you get used to it, you'll be able to apply it to your work quickly. If you have any questions or get stuck while learning, please feel free to leave a question at any time. I will continue to reinforce the content to ensure it remains helpful and immediately applicable to your practical work 🙏
