Python Logical Operators are used to combine two or more conditions and perform the logical operations using AND, OR, and NOT. Comparisons are used to compare two variables. What if we want to match more than one condition? Very simple, logical operators will do the trick for you.
The below table outlines the Python Logical Operators and or not with examples.
| Logical Operators | Description | Example |
|---|---|---|
| AND | It will return true when both conditions are true | If (age > 18 AND age <=35) |
| OR | It will return true when at least one of the conditions is true | If (age > 35 OR age < 60) |
| NOT | If the condition is true, the logical NOT operator makes it false | If age = True, then NOT( age) returns false. |
The truth table behind the Logical AND and OR operator.
| Condition 1 | Condition 2 | Condition 1 AND Condition 2 | Condition 1 OR Condition 2 |
|---|---|---|---|
| True | True | True | True |
| True | False | False | True |
| False | True | False | True |
| False | False | False | False |
Python Logical Operators Example
This example will show you how to use Logical Operators in real time. For this Python demo, we are using the IF Else statement to check the age.
>>> age = 29
# AND Example
>>> if age < 33 and age > 20:
print ("Young Man")
else:
print(" Not Eligible ")
# OR Example
>>> if age < 18 or age > 60:
print(" Not Eligible to Work ")
else:
print(" Please forward Your Resume ")
In this Python Logical Operators example program, we created a new variable called age and assigned the value 29.
age = 29
In the next line, we used the If Else Statement to check whether the age value is greater than 20 or Less than 33 using the Logical AND. If both the conditions 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 any of the statement is False, the following print statement will be displayed.
print(" Not Eligible ")
Next, we again used the If Else Statement. Still, this time, we used to check whether the age value is Less than 18 OR greater than 60 using the Logical OR. If any of the statements is TRUE, then the following print statement will print.
print(" Not Eligible to Work ")
If both conditions are False, the second print statement will be displayed. Please refer Comparison article.
print(" Please forward Your Resume ")
