Logical Operators

Logical operators act on booleans and return booleans. The logical operators are and, or and not.

Logical and

This acts on 2 booleans. It returns True if both booleans are True and False otherwise. For example:

print('True and True is', True and True)
print('True and False is', True and False)
print('False and True is', False and True)
print('False and False is', False and False)

True and True is True
True and False is False
False and True is False
False and False is False

Logical or

This operator acts on 2 booleans. It returns True if at least one of the booleans is True and False if both booleans are False. For example:

print('True or True is', True or True)
print('True or False is', True or False)
print('False or True is', False or True)
print('False or False is', False or False)

True or True is True
True or False is True
False or True is True
False or False is False

Logical not

This operator acts on a single boolean. It returns the opposite of the boolean:

print('not True is', not True)
print('not False is', not False)

not True is False
not False is True

Combining Logical Operations

Although logical operations only act on up to 2 booleans at a time, just like arithmetic operators they can be combined in a single statement. For example:

print('True and False or True is ', True and False or True)
print('True or True and False is', True or True and False)
print('not True or True and False', not True or True and False)

True and False or True is  True
True or True and False is True
not True or True and False False

Although it isn’t important for the cases above, if you need to ensure a specific order for the operations you can use brackets to group them.
