I really understand each line well. I sincerely recommend it to those who have no knowledge of coding and want to try automating work vaguely. The advantages are 1. It explains things in a way that is easy for beginners to understand. 2. The examples in the class are easy to understand and apply to work. It is easy to apply to work such as e-books, membership emails, and CS emails sent to unspecified numbers of people. 3. There are no unnecessarily difficult expressions or methods. This is the part that I am most satisfied with personally. We are not going to become Super Coding Saiyans, right? We want to quickly complete the work that is difficult through automation, and for this purpose, it explains things in a way that is easy for those who applied. This is the most satisfying of the Inflearn lectures. I hope the next lecture will have these things. 1. Sending emails only to newly registered columns in a specific sheet such as 'Today', and sending only newly entered data instead of past data 2. Sending text messages, as mentioned in the last video
