Python logical operators

This tutorial is a Python logical operators. python Logical operators are used to comparing multiple relational expressions. We can use logical operators by using that we can combine more than one relational expression and according to return true or false.

Python buil-in 3 logical operators:

1. And
2. Or
3. Not

And

And an operator is more than one relational expression and it will return true. if one of the expressions is false then it returns false.

Syntax

expression1 and expression2

Example

numbers = 105

if numbers > 100 and numbers < 150:
    print("Number is between 100 and 150")
print("Number is :",numbers)

Output:
Number is between 100 and 150
Number is : 105

Or

Or an operator is more than one relational expression and it returns true. if one of the expressions is true and the second false then it will return true.

Syntax

expression1 or expression2

Example

numbers = 105
if numbers == 100 or numbers == 105:
    print("Or operator success!")
print("Number is", numbers)
Output:

Or an operator success!
Number is 105

Not

not an operator is used to reverse the logical state of the expression.

Syntax

not expression1

Example

numbers = 150
if not numbers == 100:
    print("Not operator success!")
print("Numbers is",numbers)
Output:
Not operator success!
Numbers is 150
