Answer 2

I noticed that you don't have a single return statement in your function, which is a baaaaaaaad idea. A print statement will display a value, but will not only let the program continue to run, but also not give a program a value to use. For example, if a certain function calculates the better of two cars and prints but does not return the answer, then if you say goodCar = pickBetterCar(carA, carB), goodCar won't get an actual value. when you use functions in functions(like recursion) this will become extremely important

Answer 3

indeed (see my answer to gothery ps6 above).
you would need to return values if ps6.4(part) were inserted into the main program.
prints were just to see it work..
