Booleans and Comparisons

15 min In Progress

Learning Objectives

  • Understand True and False
  • Use comparison operators
  • Combine conditions with and, or, not

Boolean Values

Booleans represent truth values: True or False. They are the foundation of decision-making in code.

is_raining = True
has_umbrella = False
print(type(is_raining))

Comparison Operators

Use ==, !=, <, >, <=, >= to compare values and get a boolean result.

x = 10
y = 20
print(x == y)   # False
print(x != y)   # True
print(x < y)    # True
print(x >= 10)  # True

Logical Operators

Combine comparisons with and, or, and not.

age = 25
has_id = True
can_vote = age >= 18 and has_id
print(can_vote)

# not flips the value
print(not False)

📝 Exercise: Eligibility Checker

Create variables for age and a boolean has_ticket. Print whether the person can enter (age >= 13 and has_ticket).
