Introduction
This chapter will expand our understanding of programming by introducing types and literals. We’ll also learn about two additional arithmetic operators: floor division using the // operator (also called Euclidean division or integer division), and the modulo operator % (also called the remainder operator). Please note that the modulo operator has nothing to do with calculating percentages—this is a common confusion for beginners.
Learning objectives
- You will learn how to use the assignment operator and how to create and name variables.
- You will learn how to use the addition, subtraction, multiplication, division, and exponentiation operators.
- You will learn the difference between and use cases of division and Euclidian division (integer division).
- You will learn how to use the remainder or “modulo” operator.
- You will learn operator precedence in Python.
