Hello. This is instructor Choi Il-seon! Thank you so much for taking my lecture (_ _ ) I'm writing to give you some information! First, you can preview most of the "1. Python Basics" section at the following link! https://www.inflearn.com/course/it%EB%B3%B4%EC%95%88-%ED%8C%8C%EC%9D%B4%EC%8D%AC-%EC%8A%A4%EC%BF%A8/ Also, due to the structure of the inflearn site, it's difficult for me to check if you leave a question here ^^; If you leave a question on the Security Project Naver Cafe, I'll try to answer it quickly!
