For quality data analysis and visualization, I needed Python in addition to R, so I took this course. I have taken courses on Numpy, Pandas, matplotlib, etc. on other sites, but I don't know if it's because of the difference in lecture styles, but in the case of other sites, the basics were briefly explained and skipped over, so I felt disappointed. However, this course was good because I could learn and practice through examples in an easy-to-understand way, and I was able to learn comfortably because it explained from the parts where errors occur to the parts where mistakes are often made. I will have to personally study more in-depth content, but I recommend it if you want to learn the basics for data management and visualization with Python.
