Great book for anyone needing common tools used in Python and indeed in data science. My favourite chapters were 2, 3 and 4. Basically, if you are a noob like me, you should start from the chapter one and read through till chapter 4. List, dictionary, tuple comprehensions are quiet powerful as well as array with panadas and scikitlearn.
If you are looking for more in depth graphical representation of plots using pandas and skitlearn then maybe look at another book as this one is more of a back ground tools kind-a-thing.
