The Python Comparison Operators are used to compare two variables, what if we want to match 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 in Python.
The below table outlines the Python and operator, Python or operator, python not operator with examples.
|AND or Python Logical AND||It will return true when both conditions are true||If (age > 18 AND age <=35)|
|OR or Python Logical OR||It will return true when at least one of the condition is true||If (age > 35 OR age < 60)|
|NOT or Python 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
PYTHON LOGICAL AND
The following table is the truth table behind the Python Logical AND Operator
|Condition 1||Condition 2||Condition 1 AND Condition 2|
PYTHON LOGICAL OR
The following truth table is behind the Python Logical OR Operator
|Condition 1||Condition 2||Condition 1 OR Condition 2|
Python Logical Operators Example
This example will show you how to use Logical Operators in real-time. For this demo, we are using the IF Else statement.
>>> 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 ")
In this Logical Operators example program, First, we created a 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 using Python Logical AND operator. If both the condition are True, then the first print statement will display. It means age must be greater than 20 and Less than 33.
print (" Young Man ")
If anyone of the statement is False, the following print statement will be displayed
print(" Not Eligible ")
Next, we again used If Else Statement. Still, this time, we used to check whether the age value is Less than 18 OR greater than 60 using Python Logical OR operator. If anyone of the statement is TRUE then following print statement will be displayed
print(" Not Eligible to Work ")
If both the condition are False, the second print statement will be displayed.
print(" Please forward Your Resume ")
