5.6: Logical Operators

Logical operators are also called Boolean operators and there are three types.  Now it needs to be realized that Boolean data types are true or false, and other operators (like comparison operators) produce Boolean output.

Operator	Description	Example
and	returns True if both statements are true	x<5 and x>1
or	returns True if either statement is true	x<5 or x>1
not	returns True if result is false	not(x<5 and x>1)
