I am a student who is taking on a new challenge at a fairly young age. I used to do similar data analysis at my previous company, but if there were such convenient and good tools, I would have been able to increase productivity at my company. Through the instructor's lecture, I was able to learn that data analysis can be done easily, broadly, and deeply through Python notebooks. I am so grateful that it gave me a new perspective on approaching data. The lecture is so easy to understand and informative that I would like to recommend it to others.
