Operators and Expressions
Explore how Python operators enable you to manipulate data and create meaningful results. Understand arithmetic, comparison, and logical operators and how to use them properly with precedence rules. This lesson equips you to build expressions that control your program logic efficiently.
We'll cover the following...
We have learned how to store data in variables, but storing alone isn’t enough. To build software, whether it is a game, a financial calculator, or a data analysis script, we need to transform that data. Operators are the verbs of programming that allow us to combine, modify, and compare values to create new information. In this lesson, we will explore how operators in Python handle math and logic, giving us the power to turn raw inputs into meaningful results.
Arithmetic operators
At its core, a Python program is often just a series of expressions. An expression is any combination of values and operators that evaluates to a single result. Python supports all standard mathematical operations, plus a few special ones for precise control over division and powers.
Standard math: Addition (
+), subtraction (-), and multiplication (*) work exactly as expected.Exponents: To raise a number to a power (like squaring or cubing), use the double asterisk (
**).True Division (/): Always returns a float (decimal), even if the ...
