Part 2. The essentials
In the chapters that follow, we’ll show you the essentials of Python. We’ll start from the absolute basics of what makes a Python program and move through Python’s built-in data types and control structures, as well as defining functions and using modules.
The last section of this part moves on to show you how to write standalone Python programs, manipulate files, handle errors, and use classes. The section ends with chapter 16, which is a brief introduction to GUI programming using Python’s tkinter module.
