__________ is the process of inspecting data that has been input into a program in order to ensure that the data is valid before it is used in a computation.

The integrity of a program’s output is only as good as the integrity of its input. For this reason, the program should discard input that is invalid and prompt the user to enter valid data.

What does the following expression mean? x

What will be displayed after the following code is executed? total = 0 for count in range(1,4):     total += count print(total)

Both of the following for clauses would generate the same number of loop iterations. for num in range(4): for num in range(1, 5):

The first line in a while loop is referred to as the condition clause.

A Boolean variable can reference one of two values which are

A variable used to keep a running total is called a(n)

A while loop is called a pretest loop because the condition is tested after the loop has had one iteration.

Reducing duplication of code is one of the advantages of using a loop structure.
