Python Logical Operators | Tutorial Reference

How to use Python's and, or, and not operators to combine conditions in boolean expressions for effective decision-making in programs.

Logical Operators

Logical operators are the and, or, not operators.

They are used to combine conditional statements.

Operator	Description	Example
`and`	`True` if both the operands are true	`x and y`
`or`	`True` if either of the operands is true	`x or y`
`not`	`True` if operand is false (complements the operand)	`not x`

Examples

Logical AND

a = 10
b = 12
c = 0

print(a>0 and b>0 and c>0)  # False
print(a>0 and b>0 and c>=0) # True

Logical OR

a = 10
b = 12
c = 0

print(a>0 or b>0 or c>0) # True
print(a<0 or b<0 and c<0) # False
print(a<=0 or b<=0 and c<=0) # True

Logical NOT

a = 10
b = 12
c = 0

print(a>0)     # True
print(not a>0) # False
print(b>0)     # True
print(not b>0) # False
print(c>0)     # False
print(not c>0) # True
