Logical Operators

#description

Logical operators in Python are used to combine multiple conditions together to form a more complex condition that needs to be satisfied. There are three logical operators in Python, namely 'and', 'or' and 'not'.

  1. "and" logical operator:

The "and" operator returns True if both the conditions on either side of the operator are true, otherwise it returns False.

For example:

 
                    
a = 10
b = 5
c = 20
if a > b and c > a:
   print("Both conditions are true")

In this case, the condition "a > b" and "c > a" are both true, so the output of the code will be "Both conditions are true".

  1. "or" logical operator:

The "or" operator returns True if either of the conditions on either side of the operator is true, otherwise it returns False.

For example:

 
                    
a = 10
b = 5
c = 20
if a > b or c > a:
   print("At least one of the conditions are true")

In this case, at least one of the conditions - "a > b" and "c > a" is true, so the output of the code will be "At least one of the conditions are true".

  1. "not" logical operator:

The "not" operator returns True if the condition on the right side of the operator is False, and False if the condition on the right side is True.

For example:

 
                    
a = 10
b = 5
if not a == b:
    print("a is not equal to b")

In this case, the condition "a == b" is False, so the output of the code will be "a is not equal to b".
