Types of Operators in Python

 

 

Python provides us 7 popular types of operators:

 

 

·      Arithmetic Operators

 

·      Relational or Comparison Operators

 

·      Logical Operators

 

·      Assignment Operator

·      Compound Operators

 

·      Identity Operators

 

·      Membership Operators

 

 

·      Today we, discuss Logical Operators:

 

In this post, we are going to discuss Logical Operator in Python but before these, if You are not seen our video on this topic please see it first, then you will understand the concepts very well.

 

·      Logical Operators

 

·      How Logical Operators Work With Boolean Types?

 

·      How Logical Operators Work With Non-Boolean Types?

 

Logical operators are used to combining two or more conditions and perform logical operations using Logical and, Logical or and Logical not. 

 

 

Operator	Meaning
and	Greater Than
or	Less Than
not	Greater Than Equal To

 

 

The Example of Basic Relational Operators :

 

a = 40

b = 20

c = 50



print(a>b and a>c)

 

The Output:

           False

 

Another Example:

 

 

a = 40

b = 20

c = 50



print(a>b and c>a)

The Output:

 

           True

Behavior of Logical Operators With Non Boolean:

 

—  Python allows us to apply logical operators with non-Boolean types also

 

—  But before we understand how these operators work with non-Boolean types, we must understand some very important points.

 

1.    None, 0 , 0.0 ,”” are all False values.

 

2.   The return value of Logical and & Logical or operators is never True or False when they are applied to non-Boolean types.

 

3.   If the first value is False, then Logical and returns first value, otherwise it returns the second value.

 

4.   If the first value is True, then Logical or returns first value, otherwise it returns the second value.

 

5.   When we use not-operator on non-Boolean types, it returns True if it’s operand is False( in any form) and False if it’s operand is True ( in any form).

 

 

Example:

                  5 and 6

 

 

Output:

                     6

 

 

Example:

                  5 and 0

 

 

Output:

                  0

 

Example:

                  0 and 10

 

 

Output:

                  0

 

Example:

                   6 and 0

 

 

Output:

                  0

 

Example:

                   10/0 and 0

 

 

Output:

                   ZeroDivisionEror

 

Example:

                   not ‘Digital’

 

 

Output:

                   False
