Hello, I am a professional working in the retail industry who realized the importance of data analysis and spent a lot of time searching for and taking various courses. Most courses often made me fall into the illusion that I had gained skills just because I followed along to create something with Python. As a result, I found myself unable to do anything on my own after finishing those courses. However, this course was definitely different. You anticipated and explained the parts that non-majors might find difficult to understand, and I was able to master the material through the basic problem-solving exercises. I am truly grateful. Now that I have completed this course, I will review it once more and then sign up for the next course according to the data analysis curriculum. I am really looking forward to the next lecture!!
