 The Python language is not sensitive to block structuring of code. False The if statement causes one or more statements to execute only when a Boolean expression is true. … Python allows you to compare strings, but it is not case sensitive. False Nested decision statements are one way to test more than one condition. True Python uses the same symbols for the assignment operator as for the equality operator. False The not operator is a unary operator which must be used in a compound expression. False Short -circuit evaluation is only performed with the not operator. False Expressions that are tested by the if statement are called Boolean expressions. True Decision structures are also known as selection structures. True An action in a single alternative decision structure is performed only when the condition is true. True The decision structure that has two possible paths of execution is known as dual alternative Which logical operators perform short-circuit evaluation? or, and Which of the following is the correct if clause to determine whether y is in the range 10 through 50, inclusive? if y >= 10 and y <= 50: A Boolean variable can reference one of two values which are True or False What is the result of the following Boolean expression, given that x = 5, y = 3, and z = 8? x < y or z > x True What is the result of the following Boolean expression, given that x = 5, y = 3, and z = 8? x < y and z > x False What is the result of the following Boolean expression, given that x = 5, y = 3, and z= 8? not (x < y or z > x) and y < z False What does the following expression mean? x <= y x is less than or equal to y Which of the following is the correct if clause to determine whether choice is anything other than 10? if choice != 10: When using the __________ logical operator, both subexpressions must be true for the compound expression to be true. When using the __________ logical operator, both subexpressions must be true for the compound expression to be true. The __________ statement is used to create a decision structure. if In flowcharting, the _______ symbol is used to represent a Boolean expression. diamond A(n) _______ decision structure provides only one alternative path of execution. single alternative In a decision structure, the action is ______ executed because it is performed only when a specific condition is true. conditionally A(n) ______ operator determines whether a specific relationship exists between two values. relational A(n) _________ statement will execute one block of statements if its condition is true or another block if its condition is false. if-else 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. if-elif-else The logical ________ operator reverses the truth of a Boolean expression. not Boolean variables are commonly used as ______ to indicate whether a specific condition exists. flags A(n) _____ expression is made up of two or more Boolean expressions. compound
