Those 100 % beginners should skip chapters 2.2 and 2.3 because you will need to use things in chapter 3 (list, dic, ...). They are almost unsolvable only based on what you just learned in chapters 1 and 2 unless you Google a lot. It doesn't make sense to have this course structure in an introduction :(
Some of these exercises are easy enough to solve but some of them are really challenging. So my overall experience is good. Thank you for creating this course.
