and

(expression1) and (expression2)

The and operator will exclusively combine two or more comparison expressions together into a compound logical expression that results in a True value if and only if ALL statements are True. The resulting expression is therefore more exclusive than a single comparison because all comparisons must evaluate True for the entire expression to evaluate True.

Example:

a = 0
b = -1
c = 10

(b > a) and (b < c)

False AND True is False

or

(expression1) or (expression2)

The or operator will inclusively combine two or more comparison expressions together into a compound logical expression that results in a True value if and only if ANY statements are True. The resulting expression is therefore more inclusive than a single comparison because any True comparison will allow the entire expression to evaluate True.

Example:

a = 0
b = -1
c = 10

(b > a) or (b < c)

False OR True is True

not

not expression1

The not operator will negate any expression so that the resulting expression evaluates True when the original expression is False and evaluates False when the original expression is True. This operator is a single argument operator and simply reverses the boolean (true/false) value of a given expression.

Example:

a = False

not (a)

NOT False is True
