Logical Operators - Combining Truth

Card 6 of 15

What's the Function of Logical Operators?

"Logical operators let us combine multiple True/False statements. They answer: What happens when we need BOTH conditions true? Or just ONE? Or the OPPOSITE?"

The Three Logical Operators

AND

Connect dependent statements

True AND True → True
True AND False → False
False AND False → False

Both must be True

OR

Connect alternatives

True OR True → True
True OR False → True
False OR False → False

At least one must be True

NOT

Invert a statement

NOT True → False
NOT False → True

Flips the truth value

Real-World Examples

# AND - Both conditions must be true
age = 20
has_license = True
can_drive = age >= 18 and has_license  # True

# OR - At least one must be true
is_weekend = True
is_holiday = False
can_sleep_in = is_weekend or is_holiday  # True

# NOT - Flip the condition
is_raining = False
bring_umbrella = not is_raining  # True

Mental Model: Think of logical operators as gates:

AND is a strict bouncer - everyone needs ID
OR is flexible - show either ID or ticket
NOT is opposite day - yes means no, no means yes

"Logical operators let you combine simple comparisons into complex conditions. They're the building blocks for decision-making logic."
