I came across a Python course for data analysis from a third party, and I thought I would never understand Python because it started with Pandas and visualization. However, as I listened to Dave's lecture and learned the basic grammar, I realized that Python was not that difficult, and it was even fun! The concepts were explained simply in 10-minute lectures, and there were quizzes so that I could study on my own, so it was easy to grasp the concepts. I studied by watching a few lectures on my way to and from work and solving quizzes on the weekends, and it was a very useful lecture in terms of time efficiency! Since I want to strengthen my career in data analysis, I plan to continue studying with the roadmap that Dave created! Thank you for the great lecture!
