When I started my data science journey, I weighed down different options to learn about the concepts –books, online courses, tutorials, etc. I did some basic courses which were handy because I could learn through apps sitting anywhere – on a bus, or a pizza store, or just relaxing with the family in front of the TV. But something was missing – I couldn’t figure out if I were missing some concepts or getting the entire big picture. Moreover, for a more serious, detailed, and long-term learning experience, it is always better to go with books. A book is also an excellent way to get away from gadgets for some time.

## 10 Best Data Science Books

## Summary

In my experience, rather than jumping into the fine technical details of each subtopic in the first go itself, it would be nice to understand why data science is a good choice and how the whole thing works from both technical and business perspectives. The overall picture will help you choose what’s most important and where your interest lies. In my list, Data science for business and Python data analytics are two books that can give you a good start. If you have read about data science from blogs or completed the basic courses, you might want to go with Data Science from scratch or data science for dummies followed by the other books in no particular order. Each book focuses on different parts of data science and will help you gain various perspectives. Happy reading!
