I listened to it very well. I started with SQL and now I've come to Python. If the SQL lecture was difficulty level 1, Python is about 7~8 for learning from data structures to control statements, so it felt like the difficulty level was definitely higher than SQL for beginners. So I listened to the explanation of the concepts repeatedly until I understood them and solved the problems, and I understood them well. Personally, the most difficult section was section 6. I think I'll gradually understand this part as well.^^ I'll also listen to the Datalian monthly seminar and Pandas lecture diligently. Thank you~
