Logical AND Operator in Python

This tutorial will explain the syntax and use of the logical AND operator in Python. The logical AND operator returns True if the value of both operands is True, and returns False if any value of the two operands is False. The logical AND operator is used in cases where we only want to perform an action or a task if all the conditions or operands are True.

In most programming languages, i.e. C, C++, Java, and C#, etc. && is used as a logical AND operator. Unlike other programming languages, the and keyword is used as the logical AND operator in Python.

Examples of Logical and Operator and in Python

Now let’s look into the use with example codes of the logical and operator and in Python.

Suppose we have a program that performs actions based on the two variables a and b; we check values of a and b using the and keyword, as shown in the below example code.

a = 12
b = 2

if a > 0 and b > 0:
    print("a and b are greater than 0")

Output:

a and b are greater than 0

Another use of the and keyword can be where we want to check the functions’ outputs and then perform an action or task based on boolean values returned by the values.

The below example code demonstrates the use of the logical AND operator and in Python to check the boolean values returned by the functions.

func1 = True
func2 = False

if func1 and func2:
    print("Both function executed successfully")
else:
    print("Task failed")

Output:

Task failed

We can also check the values of more than two operands, i.e. if all the conditions are True using multiple logical AND operators and in Python as shown in the example code below:

cond1 = True
cond2 = True
cond3 = False
cond4 = True

if cond1 and cond2 and cond3 and cond4:
    print("All conditions are true!")
else:
    print("All conditions are not satisfied")

Output:

All conditions are not satisfied
