Boolean Values

True (On)

Boolean values are like switches - either True (ON) or False (OFF)

Boolean values are the foundation of decision-making in programming. They represent either True or False. Just like a light switch can only be on or off, a Boolean can only be True or False.

3.1 Boolean Values and Logical Operators
The foundation of decision-making in programming

What are Boolean Values?

Boolean values are a fundamental data type in Python, representing True or False.

These values are used in decision-making processes in programming, such as conditional statements and loops.

Key Features:

  • Boolean values are the foundation of binary logic, where only two states exist: True and False.
  • They help control the flow of programs through if-else statements.
  • Boolean values are the output of comparison operations like >, <, ==, and logical expressions.
Python
# Boolean values are either True or False
is_student = True
has_completed_homework = False

print("Is a student?", is_student)
print("Has completed homework?", has_completed_homework)

# Boolean from comparisons
age = 15
is_teenager = age >= 13 and age <= 19
print("Is teenager?", is_teenager)

Boolean Values

True

Boolean True

False

Boolean False

Boolean values are like light switches - they can only be ON or OFF

Everyday Example:

Think of Boolean values like light switches - they can only be ON (True) or OFF (False). When you check if you have enough money to buy ice cream, the answer is either Yes (True) or No (False).

Remember:

In Python, True and False are special keywords and must be capitalized!

Your Notes
Important concepts to remember

Boolean Values

  • Boolean values are either True or False
  • They are the foundation of decision-making in programming
  • Boolean values are capitalized in Python: True and False

Logical Operators

  • and: True if both conditions are True
  • or: True if at least one condition is True
  • not: Inverts the Boolean value (True becomes False, False becomes True)

Truth Tables

Remember the key results:

  • For and: Only True and True results in True
  • For or: Only False and False results in False
  • For not: Flips the value (not True is False, not False is True)

Operator Precedence

When multiple operators are used, they are evaluated in this order:

  1. not has the highest precedence
  2. and is evaluated next
  3. or has the lowest precedence

Use parentheses to control the order of evaluation!
