This book is a Python introductory book for Python readers at all levels. The book is divided into two parts: The first part introduces the basic concepts that you must understand when programming with Python, including the introduction of powerful Python libraries and tools such as matplotlib, NumPy and Pygal, as well as lists, dictionaries, if statements, classes, files and exceptions, code tests, and so on. The second part puts theory into practice and explains how to develop three projects, including how simple Python 2D game development can use data to generate interactive infographics, create and customize simple Web applications, and help readers solve common programming problems and confusions.

Introduction to the Author

Eric Matthes, a high school science and math teacher, lives in Alaska and teaches Python introductory courses locally. He has been writing programs since he was 5 years old.
