If you are a book lover like me, then you should start looking at data science books that are available to you for free. These books will teach you Python programming, the art of data science, and machine learning and introduce you to new tools and frameworks. Moreover, some books are built like a website so that you can explore, search and interact with the book. 


1. Learn Python the Right Way


Learn Python the Right Way is a book for beginners who are interested in learning Python but don’t know where to start. You can download the book or use a web interface to read it online. Every chapter comes with a YouTube tutorial explaining syntax and functionalities in detail.

Instead of focusing on statistics and coding, the book teaches you critical thinking. You will learn how to Refine the questions, perform exploratory data analysis, apply linear regression or random forest, and interpret the result to provide actionable insights. 

The book covers:

  1. Epicycles of Analysis
  2. Stating and Refining the Question
  3. Exploratory Data Analysis
  4. Using Models to Explore Your Data
  5. Inference: A Primer
  6. Formal Modeling
  7. Inference vs. Prediction: Implications for Modeling Strategy
  8. Interpreting Your Results
  9. Communication


3. Data Science at the Command Line


Data Science at the Command Line is my favorite, and I have written a detailed review about it in the KDnuggets blog. You can either buy a book from Amazon or read the online version for free. The online version is interactive and comes with interesting features.
