Booleans in Python are a fundamental data type that represents one of two values: True or False. These values are used to evaluate expressions and control the flow of a program with conditional statements like if, while, and others.
Basic Usage of Booleans
In Python, booleans are defined by the bool data type and can be directly assigned to variables without any additional declaration. Here's a simple example of boolean assignment and usage:
# Assigning boolean valuesis_active = Trueis_inactive = False# Using booleans in conditional statementsif is_active:print("The user is active.")else:print("The user is inactive.")Evaluating Expressions with Booleans
Expressions in Python are evaluated to a boolean value. For instance, comparison operators (==, !=, <, >, <=, >=) return a boolean result based on the comparison:
# Comparison expressionsprint(10 > 9) # Outputs: Trueprint(10 == 9) # Outputs: Falseprint(10 < 9) # Outputs: FalseThe bool() Function
