Python - Logical Operators

Python has logical operators to combine or compare boolean values.

• and - AND
• or - OR
• not - NOT

The 'and' and 'or'

The 'not'

The 'not' logical operator just inverts the boolean.

print(not False) # True
print(not True) # False 

Examples

age0 = 69
age1 = 169
print(age0 > 0 and age0 < 100) # True
print(age1 > 0 and age1 < 100) # False

age0 = 69
age1 = 169
print(age0 <= 0 or age0 >= 100) # False
print(age1 <= 0 or age1 >= 100) # True

isPython = True
isJavaScript = False

print(not isPython) # False
print(not isJavaScript) # True
