What this book covers

Chapter 1, Review of the Core Modules of NumPy and Pandas, introduces two of three main modules used for data manipulation, using real dataset examples to show their relevant capabilities.

Chapter 2, Review of Another Core Module – Matplotlib, introduces the last of the three modules used for data manipulation, using real dataset examples to show its relevant capabilities.

Chapter 3, Data – What Is It Really?, puts forth a technical definition of data and introduces data concepts and languages that are necessary for data preprocessing.

Chapter 4, Databases, explains the role of databases, the different kinds, and teaches you how to connect and pull data from relational databases. It also teaches you how to pull data from databases using APIs.

Chapter 5, Data Visualization, showcases some analytics examples using data visualizations to inform you of the potential of data visualization.

Chapter 6, Prediction, introduces predictive models and explains how to use Multivariate Regression and a Multi-Layered Perceptron (MLP).

Chapter 7, Classification, introduces classification models and explains how to use Decision Trees and K-Nearest Neighbors (KNN).
