Logical Operators in Python

 

Logical Operators in Python

Python provides three logical operators:

 And, Or, and Not. 

These operators are used to combine conditional statements and evaluate expressions based on Boolean logic. 

And operator:

The and operator returns True if both operands are True.

If either or both operands are False, it returns False.

This operator exhibits short-circuiting behavior: if the first operand is False, the second operand is not evaluated.

Python

    x = 5

    y = 10

    print(x > 0 and y < 15)  

Output: True

    

print(x > 0 and y < 5)   

 

Output: False

Or operator:

The or operator returns True if at least one of the operands is True. 

It returns False only if both operands are False.

This operator also exhibits short-circuiting behavior: if the first operand is True, the second operand is not evaluated.

Python

    x = 5

    y = 10

    print(x > 0 or y < 5)    

 Output: True

    print(x < 0 or y < 5)   

Output: False

Not operator:

The not operator is a unary operator, meaning it operates on a single operand.

It reverses the logical state of its operand: if the operand is True, not returns False, and if the operand is False, not returns True.

Python

    is_sunny = True

    print(not is_sunny)      

Output: False

    is_raining = False

    print(not is_raining)    

 Output: True

Precedence:

The order of precedence for logical operators in Python, from highest to lowest, is: not, and, or. This means not operations are evaluated first, followed by and operations, and finally or operations. Parentheses can be used to override this default precedence.
