Booleans in Python

In this lesson, you will learn about Booleans in python and some of the Boolean functions in python and how to use them in your programs.

Booleans in Python

If you need to find whether the given condition is true or false, Booleans are go to choice in any programming language. Python Boolean is a built-in data type, consisting of two values i.e. True or False. Generally.

Example:

if 1==0:

print(True) 

else:

print (False)

bool() function in Python

bool() function in python is an inbuilt function that can be used to check the conditions. Using the bool() function, we can evaluate values and variables.

Syntax:

bool([x])

Instead of True and False, you can also use integers and Floats as Booleans. The bool() function, interprets zero as False and any other value including negative integers as True.

Boolean Operators

Boolean operations can be performed using the following operators.

• or
• and
• not
• == (equivalent)
• != (not equivalent)

OR Operator

The ‘or’ operator in boolean returns True if any one of the inputs is True else returns False.

And Operator

The ‘and’ operator in Boolean returns False if any one of the inputs is False else returns True.

Not Operator

The NOT operators in Boolean returns the opposite value. i.e. if the condition is true it returns false and vice versa.

Now let us understand the Boolean concept with the help of a simple program using the bool() function in python.

Input:

[gamipress_button type=”submit”  label=”Run Code Snippet” onclick=”window.open(‘https://coderseditor.com/?id=1189′,’_blank’)”]

a=int(input("Enter the value of a:"))

b=int(input("Enter the value of b:"))

print(bool(a==b))

print(bool(a!=b))

print(bool(a or b))

print(bool(a and b))

Output

Enter the value of a:23
Enter the value of b:32
False
True
True
True

Here the result for a or b and a and b are true because Boolean takes an integer value as True and zero as false.
