Introduction
In this chapter, we will present vital Python concepts; that is, the core elements that everyone needs to know when starting to code. We will cover a breadth of topics while focusing on math, strings, conditionals, and loops. By the end of this chapter, you will have a strong foundation in Python, and you will be able to write significant Python programs as you continue with the rest of this book.
You will start with a very famous developer example, Python as a calculator. In addition to the standard operations of addition, subtraction, multiplication, division, and exponentiation, you will learn integer division and the modulus operator. By using only basic Python, you can outperform most calculators on the market.
Next, you’ll learn about variables. Python is dynamically typed, meaning that variable types are unknown before the code runs. Python variables do not require special initialization. The first variables we will look at will be integers, floats...
