Exercise 16.6. Write a function calledmul_timethat takes a Time object and a number and returns a new Time object that contains the product of the original Time and the number.
Then usemul_timeto write a function that takes a Time object that represents the finishing time in a race, and a number that represents the distance, and returns a Time object that represents the average pace (time per mile).
Exercise 16.7. Thedatetimemodule providesdateandtimeobjects that are similar to the Date and Time objects in this chapter, but they provide a rich set of methods and operators. Read the documentation athttp: // docs. python. org/ 2/ library/ datetime. html.
- Use thedatetimemodule to write a program that gets the current date and prints the day of the week.
- Write a program that takes a birthday as input and prints the user’s age and the number of days, hours, minutes and seconds until their next birthday.
- For two people born on different days, there is a day when one is twice as old as the other. That’s their Double Day. Write a program that takes two birthdays and computes their Double Day.
- For a little more challenge, write the more general version that computes the day when one person is n times older than the other.
