Logical Operators

Logical operators combine boolean values: and, or, and not.

and

True only when BOTH sides are true:

python
print(5 > 3 and 5 < 10)

### True
print(5 > 3 and 5 > 10)

### False

or

True when AT LEAST ONE side is true:

python
print(5 > 3 or 5 > 10)

### True
print(5 < 3 or 5 > 10)

### False

not

Flips a boolean:

python
print(not True)

### False
print(not (5 > 3))

### False

A real-world example

python
age = 25
has_ticket = True
if age >= 18 and has_ticket:
    print("Welcome in!")

Truth table for and

TL;DR

• and needs both true.
• or needs at least one true.
• not flips the value.
• Use them to combine conditions.
