Program 1: Liberty Bell Slot Machine Simulation
- Due Date: Wednesday, September 18th no later than 11:58 p.m.
- Partner Information: You may complete this assignment
individually or with exactly one partner. If you work with a partner,
you must both be enrolled in the same lab section or you
will both lose 10 points.
- Submission Instructions (working alone):
Upload your solution, entitled YourFirstName-YourLastName-Program1.py
to the BrightSpace Program 1 Dropbox.
- Submission Instructions (working with one lab mate who is in your
same lab section):
Upload your solution, entitled
YourFirstName-YourLastName-PartnerFirstName-PartnerLastName-Program1.py to the BrightSpace Program 1 Dropbox.
Note: If you work with a partner, only one person needs to submit a
solution. If you both submit a solution, the submission that will be
graded is the one from the partner whose last name comes alphabetically
- Deadline Reminder:
Once the submission deadline passes, BrightSpace will no
longer accept your Python submission and you will no longer
be able to earn credit. Thus, if you are not able to fully complete
the assignment, submit whatever you have before the deadline so that
partial credit can be earned.
- To solve this problem, you need to understand the following
Python concepts: data types, functions, selection statements
- Charles Fey constructed the first slot machine in
1895. The original machine consisted of three spinning reels
containing a total of five symbols: horseshoes, diamonds, spades,
hearts and a bell (the Liberty Bell), from which this machine took
its name. It cost 5 cents to play and the payouts worked as follows:
- three Liberty Bells: 50 cents
- three hearts: 40 cents
- three diamonds: 30 cents
- three spades: 20 cents
- three horseshoes: 10 cents
- two horseshoes and any other one symbol: 5 cents
- all other combinations: nothing
- To learn more about a subsequent, six-symbol Liberty Bell slot machine,
check out this wikipedia article.
- Download Program1.py, rename it
according to the instructions above, and make sure you fully
- Write the missing spin_payout function such that it
returns the correct payout for any spin.
- Write the missing simulate function such that it
simulates the handle of the slot machine being pulled the specified number
of times. The simulation may assume that for each reel,
the probability of generating any of the five symbols is the
same. Once the simulation is finished, the function should
print a message stating how much money can be expected to be won
for each $1 spent.
- Here is a sample transcript of the
program running. Your solution should match the output format
exactly. However, because of randomness, the expected winnings
per dollar spent might vary each time the program is run.
Grading - 100 points
- 50 points - Each of the ten test spins is calculated correctly
in a general fashion. (5 points each - all or nothing.)
- 20 points - The spin_payout function conforms to its comment
(5 points), uses meaningful user chosen names (5 points),
uses if constructs effectively (5 points) and is as simple
as possible (5 points).
- 15 points - The simulate function conforms to its comment (5 points),
uses meaningful user chosen names (5 points), and is as simple
as possible (5 points).
- 5 points - With the exception of the expected winnings, the output
format matches the output format of the transcript exactly.
All or nothing.
- 5 points - The expected winning is displayed with two digits to the
right of the decimal. All or nothing.
- 5 points - The submitted file is named correctly. All or nothing.
- The points you earn from the grading scale above will be
multiplied by .9 for a maximum of 90 points.
- The other 10 points can be earned by enhancing the
assignment in a creative, non-trivial manner.
- In the BrightSpace Dropbox comment box, describe
your enhancement clearly. (You must include this comment
to earn the additional points.)
