  • Exercise \(\PageIndex{1}\)

    Assume that we execute the following assignment statements:

    width = 17
    height = 12.0
    delimiter = '.'

    For each of the following expressions, write the value of the expression and the type (of the value of the expression).

    1. width/2
    2. width/2.0
    3. height/3
    4. 1 + 2 * 5
    5. delimiter * 5

    Use the Python interpreter to check your answers.

    Exercise \(\PageIndex{2}\)

    Practice using the Python interpreter as a calculator:

    1. The volume of a sphere with radius r is 4/3 π r3. What is the volume of a sphere with radius 5? Hint: 392.7 is wrong!
    2. Suppose the cover price of a book is $24.95, but bookstores get a 40% discount. Shipping costs $3 for the first copy and 75 cents for each additional copy. What is the total wholesale cost for 60 copies?
    3. If I leave my house at 6:52 am and run 1 mile at an easy pace (8:15 per mile), then 3 miles at tempo (7:12 per mile) and 1 mile at easy pace again, what time do I get home for breakfast?
