Again, a very important real-world skill that I want you to develop in this course is the ability to deal intelligently with under-specified tasks. So if the author asks you to write a program to make random drawings, give it a sensible, self-descriptive name like randomDrawings.py, and think of the simplest program you can write to solve the task as specified. If the author asks you to demo your robot program to a friend outside of class, you can just run it for me.
Pro-tip: When copy/pasting a single line of code that wraps (appears as two lines) in the textbook, make sure to turn it back into a single line in your programs and in the Shell, through judicious use of the delete key. You'll see some examples of this problem on page 86.
Question 4.1: Hackers, like cats, can never leave well-enough alone. So when the author says on page 67 that “The value returned by currentTime is a number that represents the seconds elapsed since some earlier time, whatever that is”, we get curious about that last bit.1 Can you convert the value returned by currentTime into a number of years, to determine what “that earlier time” was? Google unix time to check your answer.
