Exam 3: Decision Structures and Boolean Logic

Python allows you to compare strings,but it is not case sensitive.

Nested decision statements are one way to test more than one condition.

Which logical operators perform short-circuit evaluation?

In Python the __________ symbol is used as the equality operator.

The logical __________ operator reverses the truth of a Boolean expression.

Decision structures are also known as selection structures.

A(n)__________ decision structure provides only one alternative path of execution.

In flowcharting,the __________ symbol is used to represent a Boolean expression.

A Boolean variable can reference one of two values which are

In Python the __________ symbol is used as the not-equal-to operator.

The decision structure that has two possible paths of execution is known as

The if statement causes one or more statements to execute only when a Boolean expression is true.

An action in a single alternative decision structure is performed only when the condition is true.

Python uses the same symbols for the assignment operator as for the equality operator.

Python provides a special version of a decision structure known as the __________ statement,which makes the logic of the nested decision structure simpler to write.

What is the result of the following Boolean expression,given that x = 5,y = 3,and z = 8? X < y or z > x

Short -circuit evaluation is only performed with the not operator.

Multiple Boolean expressions can be combined by using a logical operator to create __________ expressions.

A(n)__________ operator determines whether a specific relationship exists between two values.

When using the __________ logical operator,one or both of the subexpressions must be true for the compound expression to be true.
