Hello Chanho :) I'm so glad it was helpful 😀😀 I've extended the course period to Chanho's account!! (If you feel that the period is not enough, please leave a message in the Slack link in the lecture or on the Inflearn lecture bulletin board and I will extend the period.) In the field, if you write queries one by one while looking at them with your own eyes, you can extract the data you want and improve your skills even more 😀 Thank you ^^
