2. Python Basics

Python fundamentals set the stage for everything that follows in this book. In this chapter sequence you will learn:

• Python core syntax

• control flow,

• built-in data structures (lists, tuples, and dictionaries),

• conditionals and iteration, and finish by

• defining functions.

Together these lessons give you the building blocks to write readable programs and prepare for data-focused work in later chapters.

Here blow is a Python syntax cheatsheet for beginners. Browse over it and see how many of the concepts/details you already know.
