6. Where do parameters get their values?

   from the corresponding argument in the function call

7. What is an expression?

   anything that can be turned into a value

8. If a variable is defined inside a function, can another function see the value of that variable?

   no

9. If you typed the following in the Python interactive mode, what would the result be?

   True and False

   False

10. What do you call the functions that are always available in Python and DO NOT have to be imported?

    built-in functions

11. What arithmetic operators have the highest precedence (parentheses are NOT operators)?

    True

13. What is the result of the following calculation in Python's interactive mode?

    7 // 2

    3

14. What do you call a variable that is defined inside a function?

    a local variable

15. Write the Python boolean literals.

    True and False

16. Define the function print_grade that takes one parameter, score.
    This script should contain a SINGLE if statement which prints the letter grade for each range of scores according to the following table

    A    >= 90
    B    >= 80
    C    >= 70
    D    >= 60
    F    <  60

17. Write a for loop that prints the odd numbers from 1 to 15.
    You MUST use the range function with 3 arguments.
    

    for num in range(1, 16, 2):
       print(num)

18. Write a while loop that prints the numbers 5, 10, 15, each on a separate line.
    You CANNOT use the range function here.
    You also CANNOT use a list.
    You will need to give a starting value to the variable num before entering the loop.
    num will be tested tested at the start of the while loop.
    

    num = 5
    while num < 15:
       print(num)
       num += 5

19. Write ONE if statement that prints "A" if the variable called score is 90 or more.
    Prints "B" when score is between 89 and 80.
    Prints "C" when score is between 79 and 70.
    Prints "D" when score is between 69 and 60.
    Otherwise it prints "F".
    Assume that score already has a value.

    if score >= 90:
        print("A")
    elif score >= 80:
        print("B")
    elif score >= 70:
        print("C")
    elif score >= 60:
        print("D")
    else:
        print("F")
