Python Booleans

Python Booleans

Introduction

Python Booleans are used for evaluating expressions and conditional statements. A Boolean value can either be True or False. In this article, we will discuss how to use Booleans in Python programming.

Boolean Operators

There are three different Boolean operators in Python: and, or, and not.

The and Operator

The and operator returns True if both of its operands are True. For example:

a = 5
b = 7
if a > 4 and b > 6:
    print("Both conditions are True")

In this example, both a > 4 and b > 6 are True, and therefore the code inside the if statement block will run and print “Both conditions are True”.

The or Operator

The or operator returns True if at least one of its operands is True. For example:

a = 5
b = 7
if a > 6 or b > 8:
    print("At least one condition is True")

In this example, neither a > 6 nor b > 8 is True, and therefore the code inside the if statement block will not run.

The not Operator

The not operator returns the opposite value of its operand. For example:

a = 5
b = 7
if not a > 6:
    print("a is not greater than 6")

In this example, a > 6 is False, and therefore the not operator returns True, and the code inside the if statement block will run and print “a is not greater than 6”.

Boolean Values

In Python, True represents the value true, and False represents the value false. For example:

a = True
b = False
if a:
    print("a is True")
if not b:
    print("b is False")

In this example, both a and b have been assigned Boolean values, and the corresponding if statements will evaluate to true and false, respectively.

Comparing Values with Booleans

Boolean values are often used to compare the values of variables or expressions. For example:

a = 5
b = 7
if a == b:
    print("a is equal to b")
elif a > b:
    print("a is greater than b")
else:
    print("b is greater than a")

In this example, the values of a and b are compared using the ==, >, and < operators, and the resulting Boolean values are used to determine which block of code to run.

Conclusion

Python Booleans are a fundamental part of Python programming, and are used to evaluate expressions and conditional statements. By understanding how Boolean values and operators work, you can make your Python code more powerful and flexible.
