Hello. You purchased the package, but I was not able to give you a satisfactory course experience. This course was created based on my experience teaching at various companies both online and offline, creating various contents, and receiving feedback. Although you purchased the package, this course includes basic content as some people are new to Python data analysis. Also, even if you have learned how to use basic Python data analysis tools, I have seen many people have difficulty applying it to other data, so the course is structured so that you can apply it repeatedly to other data. After looking at your course history, I noticed that you have not completed the course yet, but if you continue to take the course and are still not satisfied, I am willing to personally give you a refund. Also, most of my paid courses are not created once and then finished, but are continuously updated. I will take your feedback into consideration when updating.
