I am a Data Scientist who usually codes in R. It was a challenge to get comfortable enough in python code to review the book. Python come in a lot of flavors. I used Anaconda Launcher to run jupyter notebooks. The code is on the publishers page.
With broad strokes in six chapters it cover the fundamentals of Data Science using python. The pretty blue mosaic tile swirl on the cover catches your eye.
My favorite chapter is chapter five on Social Network Analysis. I like the table on graph types, node and edges. For example Twitter, a directed graph, people are nodes and followers are edges. Very useful table for writing code.
Get the code, run the notebooks, have fun.
