Which of the following statements is false?
a. The function modify_elements multiplies each element of its list argument by 2: def modify_elements(items): """"Multiplies all element values in items by 2.""" for i in range(len(items)): items[i] *= 2 b. Part (a)’s function modify_elements’ items parameter receives a reference to the original list, so the statement in the loop’s suite modifies each element in the original list object. c. When you pass a tuple to a function, attempting to modify the tuple’s immutable elements results in a TypeError. d. Tuples may contain mutable objects, such as lists, but those objects cannot be modified when a tuple is passed to a function.
Computers are playing an increasing role in education. The use of computers in edu- cation is referred to as computer-assisted instruction (CAI). Write a program that will help an elemen- tary school student learn multiplication. Use the random module to produce two positive one-digit integers. The program should then display a question, such as How much is 6 times 7? The student then types the
answer. Next, the program checks the student’s answer. If it is correct, print the string "Very good!" on the screen and ask another multiplication question. If the answer is wrong, display "No. Please try again." and let the student try the same question again repeat- edly until the student finally gets it right. A separate function should be used to generate each new question. This method should be called once when the program begins execution and each time the user answers the question correctly. [Hint: To convert the numbers for the problem into strings for the question, use function str. For example, str( 7 ) returns "7".] What will be an ideal response?
