Getting Started
Visit Piazza and download the “bare bones” file lab5.py onto your computer. Open lab5.py in PyCharm and
fill in the following information at the top:
1. your first and last name as they appear in Blackboard
2. your Net ID (e.g., jsmith)
3. your Stony Brook ID # (e.g., 111999999)
4. the course number (CSE 101)
5. the assignment name and number (Lab #5)
Submit your final lab5.py file to Blackboard by the due date and time. Late work will not be graded. Code that
crashes and cannot be graded will earn no credit.
Part I: FizzBuzz (20 points)
Write the function fizz buzz(), which takes three arguments in the following order:
• max fizz buzz: a positive integer
• fizz: a prime number
• buzz: a prime number
The function returns a list of integers and strings until a condition described below is met. Suppose this list is
called result. The following rules are applied:
• If a number is a multiple of both fizz and buzz, then append ’fizzbuzz’ to result.
• If a number is a multiple of fizz only, then append ’fizz’ to result.
• If a number is a multiple of buzz only, then append ’buzz’ to result.
• If a number is not a multiple of either fizz or buzz, then simply append the number to result.
CSE 101 Lab #5 Page 1
Strings and integers are appended to result until ’fizz buzz’ has been appended max fizz buzz times.
You will want to use a while-loop to repeat applying the above rules while a counter is less than max fizz buzz.

Part II: Filthy Rich (20 points)
As a Real Estate Tycoon you are planning to purchase properties in different blocks around the city. However,
there is a maximum number of properties you can buy based on your budget. Write a function mass purchase()
that takes arguments in the following order:
• city: A list of lists of integers representing prices of properties. Each integer represents the price of a
building in millions of dollars ($M).
• budget: An integer that represents the maximum amount in dollars (in $M) you can spend on purchasing
bulidings.
The function iterates over the list of lists, visiting the values in this order: city[0][0], city[0][1],
city[0][2], …, city[1][0], city[1][1], city[1][2], … Note that it is not necessarily the case
that every “row” (e.g., city[i]) has the same number of properties.
As the function “visits” each integer value, it adds the value to a running total, provided that doing so would
not cause the total to exceed the budget. Adding an integer to the total therefore corresponds with purchasing
a building. Each time a building is purchased, the indexes of that building in the list are appended to a list
(let’s call it result). For example, suppose that the function decides to purchase the buildings city[0,2],
city[1,0] and city[3,7]. The return value of the function (result) would be the list of lists [[0,2],
[1,0], [3,7]]. Important: the buildings that are purchased must be added in the order specified in the
previous paragraph.
Hint: use nested for-loops, where the outer loop iterates over the list city and the inner loop iterates over a
sub-list of city (e.g., a particular city[i]). Part of the code you will need to write is given below:
result = []
for i in ________ :
for j in ________ :
if ________ :
result.append([i, j])
