8. Boolean Variables

• We can store true and false

• Variables of this type are called logical or boolean

• In Python, we can initialize variables of this type with True or False

• Note that the T and F are capitalized, any other form generates a syntax error

8.1. Relational Operators

Relational Operators

Operator	Operation	Mathematical equivalent symbol
==	equal	=
>	greater than	>
<	less than	<
!=	not equal	<>
>=	greater or equal	>=
<=	less or equal	<=

• Note that the equality operator is two equals (==)

8.3. Important Example

• >= or <= for equal values

Activity: CodeLens 8.3.1 (cl_l05_8b_en)

8.4. Example

• We can use relational operators to initialize logical variables
