reviews of learn python3 the hard way

Almost every time，I try my best to write a long review of the book I have read. But this time I want to have a short one.
learn python3 the hard way is a book which will teach you how to start to write codes. It has many exercises,through which you can build your habits of writing codes, revising codes, etc. Try hard as you may to type every character by yourself and you will gain more!
