You made a good quiz. The difficulty level is not too high, about <easy~medium>, but it was fun because it was a task related to real life, and the content I learned in the chapter felt like it was not just a lump of knowledge, but a tool that I could use in the future. As you said in the lecture information, you only teach the very basics about Python, and for the content that is highly useful (probably important in practice), you hint at ways to study more. Thank you for the great lecture. I look forward to the application part.
