Logical Operators

Explore how logical operators and, or, and not work in Python to combine and invert boolean expressions. Understand their role in decision-making and how compound logical assignment operators simplify code by combining logical operations with assignments. This lesson builds a foundation for mastering conditional program execution.

We'll cover the following...

Logical operators enable us to make decisions based on multiple conditions. Python provides three logical operators: and, or, and not. These operators help combine or invert boolean expressions, making our code more powerful and versatile. Below, we can find the basic logical operators in order of precedence. The operator listed higher will be computed first.

Operator

Purpose

not

Inverts the boolean value of its operand; returns True if the operand is False, and False if the operand is True

and

Returns True if both operands are True, otherwise returns False

or

Returns True if at least one of the operands is True, otherwise returns False

Logical expressions

Logical expressions are formed using booleans and logical ...
