Logical operators in Python

  • by

Python Logical operators are used to combine conditional statements. Python has three Logical operators the and, or, not operators.

OperatorMeaningExample
andTrue if both the operands are truex and y
orTrue if either of the operands is truex or y
notTrue if operand is false (complements the operand)not x

Logical operators in Python

Simple example code performs Logical AND, Logical OR, and Logical NOT operations.

x = True
y = False

print('x and y is',x and y)

print('x or y is',x or y)

print('not x is',not x)

Output:

Logical operators in Python

Check multiple conditions at the same time.

price = 9.99

print(price > 9 and price < 10)

print(price > 10 or price < 20)

print(not price > 10)

Precedence of Logical Operators

When you mix the logical operators in an expression, Python will evaluate them in the order which is called the operator precedence.

The following shows the precedence of the not, and, and or operators:

OperatorPrecedence
notHigh
andMedium
orLow

Python will evaluate them from the left to right:

a or b and cmeansa or (b and c)
a and b or c and dmeans(a and b) or (c and d)
a and b and c or dmeans((a and b) and c) or d
not a and b or cmeans((not a) and b) or c
