Which of the following statements is false?
a. Built-in function reversed returns an iterator that enables you to iterate over a sequence’s values backward.
b. The following list comprehension creates a new list containing the squares of numbers’ values in the same oder as the list:
numbers = [10, 3, 7, 1, 9, 4, 2, 8, 5, 6]
reversed_numbers = [item for item in reversed(numbers)]
c. Built-in function zip enables you to iterate over multiple iterables of data at the same time. The function zip receives as arguments any number of iterables and returns an iterator that produces tuples containing the elements at the same index in each.
d. The following call to zip below produces the tuples ('Bob', 3.5), ('Sue', 4.0) and ('Amanda', 3.75) consisting of the elements at index 0, 1 and 2 of each list, respectively:
names = ['Bob', 'Sue', 'Amanda']
grade_point_averages = [3.5, 4.0, 3.75]
zip(names, grade_point_averages)
b. The following list comprehension creates a new list containing the squares of numbers’ values in the same oder as the list:
numbers = [10, 3, 7, 1, 9, 4, 2, 8, 5, 6]
reversed_numbers = [item for item in reversed(numbers)]

Write an application that implements a trip-time calculator. Define and use a class TripComputer to compute the time of a trip. TripComputer should have the private attributes
• totalTime—the total time for the trip • restStopTaken—a boolean flag that indicates whether a rest stop has been taken at the end of the current leg and the following methods: • computeLegTime(distance, speed)—computes the time for a leg of the trip having a given distance in miles and speed in miles per hour. If either the distance or the speed is negative, throws an exception. • takeRestStop(time)—takes a rest stop for the given amount of time. If the time is negative, throws an exception. Also throws an exception if the client code attempts to take two rest stops in a row. • getTripTime—returns the current total time for the trip. This structure of this project is similar to project 9. Even though the class TripComputer is pretty simple, developing and testing it first is advisable.
