Python Logical Operators

The Python Comparison Operators are used to compare two variables, what if we want to compare more than one condition? Very simple, python logical operators will do the trick for you.

Python Logical Operators are used to combine two or more conditions and perform the logical operations using Logical AND, Logical OR and Logical NOT. Below table describes them

Python Logical Operators	DESCRIPTION	EXAMPLE
AND or Logical AND	It will return true when both conditions are true	If (age > 18 AND age <=35)
OR or Logical OR	It will returns true when at-least one of the condition is true	If (age > 35 OR age < 60)
NOT or Logical NOT	If the condition is true, logical NOT operator makes it false	If age = True then NOT( age) returns false.

Let us see the truth tables behind the Python Logical Operators. Please refer them for better understanding

LOGICAL AND

Following table is the truth table behind the Logical AND Operator

Condition 1	Condition 2	Condition 1 AND Condition 2
True	True	True
True	False	False
False	True	False
False	False	False

LOGICAL OR

Following table is the truth table behind the Logical OR Operator

Condition 1	Condition 2	Condition 1 OR Condition 2
True	True	True
True	False	True
False	True	True
False	False	False

Python Logical Operators Example

This example will show you, How to use Python Logical Operators in real-time

PYTHON CODE

>>> age = 29
# Logical AND Example
>>> if age < 33 and age > 20:
	print ("Young Man")
else:
	print(" Not Eligible ")

# Logical OR Example
>>> if age < 18 or age > 60:
	print(" Not Eligible to Work ")
else:
	print(" Please forward Your Resume ")

OUTPUT

ANALYSIS

First we created new variable called age and assigned value 29

 age = 29

In the next line we used If Else Statement to check whether the age value is greater than 20 and Less than 33 (Logical AND). If both the condition are True then first print statement will be displayed. It means age must be greater than 20 and Less than 33.

print (" Young Man ")

If any one of the statement is False, following print statement will be displayed

print(" Not Eligible ")

In the next line we again used If Else Statement but this time we used to check whether the age value is Less than 18 OR greater than 60 (Logical OR). If any one of the statement is TRUE then following print statement will be displayed

print(" Not Eligible to Work ")

If both the condition are False, second print statement will be displayed.

print(" Please forward Your Resume ")
