Boolean expressions play a fundamental role in programming, allowing developers to make decisions based on logical conditions.

In this article, we’ll explore Python’s boolean expressions, how they work, and practical examples of their usage.

Understanding Boolean Expressions

A boolean expression is an expression that evaluates to either True or False. In Python, boolean expressions are used in conditional statements, loops, and logical operations.

Boolean Operators in Python

Python provides several boolean operators for combining and manipulating boolean values:

1. and: Returns True if both operands are True.
2. or: Returns True if at least one operand is True.
3. not: Returns the negation of the operand; True becomes False and vice versa.

Example 1: Using Boolean Operators:

x = 5
y = 10
print(x > 3 and y < 20)  # Output: True
print(x > 3 or y > 20)    # Output: True
print(not x > 3)          # Output: False
