Python 3 – Two Python Questions
Hello!
There are TWO Python 3 questions that I need to be completed.
I will attach the PDF with instructions and a ZIP file with the required .py file needed to complete the home.
Thank you!

CSC 242-801: Introduction to Computer Science II
Lab exercise set 1
Due Thursday, January 7th, 10 pm
Logistics
These exercises should be completed during the lab on Thursday, January 7th. The lab template will be available
beginning at 5 pm on D2L, and you should start the lab immediately after finishing the quiz. A grading rubric for lab
sessions is available.
The exercises for this week are a review of material covered in CSC 241. You should find them to be straightforward. If
that’s not the case, please be sure to review your CSC 241 materials as a part of your first week of work for this class. I
have posted recordings reviewing crucial CSC 241 topics in the Course recordings sections on the D2L site.
You are allowed and encouraged to work in groups on lab exercises. If you do work with someone, you must include
the name(s) of your collaborator(s) at the top of the file you submit. For more information about collaboration policies in
this class, see the Academic Integrity Pledge posted to the D2L site.
Begin the lab by downloading the zip file found on the D2L site. It contains a template file csc242lab1.py.
1. Write a function cleanData() that takes a two-dimensional list of numbers (e.g., a list of lists containing float and
int values) representing measurements and modifies the list so that each negative (< 0) number is replaced by a 0.
Any zeros or positive values in the list will be unchanged. The function does not return any values but instead
modifies the list provided as a parameter. The function is also not allowed to create a new list, since the parameter
list must be modified. You should assume that the list given to the function will contain numbers, and your function
does not have to behave reasonably on any parameter other than a two-dimensional list of numbers. Note that the
list may be empty, in which case it will obviously not be changed by the function. The following shows some
sample interactions with the completed function. Note that these examples are just that, and your function must
work correctly on any two-dimensional list of numbers:
>>> lst1 = [[1, -2, 3, -4], [5.5, -6.6], [0, -10, 0, 10]]
>>> cleanData(lst1)
>>> lst1
[[1, 0, 3, 0], [5.5, 0], [0, 0, 0, 10]]
>>> lst2 = [[-1], [0], [2], [0], [-3], [0], [4], [0], [5]]
>>> cleanData(lst2)
>>> lst2
[[0], [0], [2], [0], [0], [0], [4], [0], [5]]
>>> lst3 = [[3.3, 4.4, 5.5, 6.6], [0, -1, 0, -2, 0], [3.1415, 7.777]]
>>> cleanData(lst3)
>>> lst3
[[3.3, 4.4, 5.5, 6.6], [0, 0, 0, 0, 0], [3.1415, 7.777]]
>>> lst4 = []
>>> cleanData(lst4)
>>> lst4

2. Write a function nameGame() that takes a list of strings representing names as a parameter and plays a guessing
game with the user. The function chooses a random name from the list and then repeatedly prompts the user to
enter a name. If the user’s entry is not the name randomly chosen by the function, the function prints a message
sharing that information with the user and continues the game. If the user’s entry matches the name chosen from
the list, the function prints a message to that effect and stops. The function should not change the name chosen
between rounds of the game. The names in the list provided as a parameter can be in any case, as can the name(s)
entered by the user during the game. The function should compare names without taking case into account, so that
names match if they have the same sequence of letters in the same order. If the list of names provided is empty, the
function simply prints a message to that effect and does not do anything else. The function should not change the
list provided as a parameter. The following shows several sample runs of the function. Note that your runs may
differ in the name chosen since the name is chosen randomly:
>>> nameGame([])
I’m sorry, but I can’t play a game with an empty list.
>>> nameGame([‘Annika’, ‘JoJo’, ‘erin’, ‘AMBER’, ‘LaRue’])
Enter your guess: ERIN
That’s not it. Please try again.
Enter your guess: jojo
That’s not it. Please try again.
Enter your guess: larue
That’s not it. Please try again.
Enter your guess: ANNIKA
You got it! Thanks for playing.
>>> nameGame([‘Sigrid’, ‘Andre’, ‘Jaime’, ‘Patty’])
Enter your guess: SIGRID
That’s not it. Please try again.
Enter your guess: jaime
That’s not it. Please try again.
Enter your guess: andRE
That’s not it. Please try again.
Enter your guess: pattY
You got it! Thanks for playing.
>>> nameGame([‘Sigrid’, ‘Andre’, ‘Jaime’, ‘Patty’])
Enter your guess: Patty
That’s not it. Please try again.
Enter your guess: andre
That’s not it. Please try again.
Enter your guess: SIGrid
That’s not it. Please try again.
Enter your guess: jaime
You got it! Thanks for playing.

You must submit your solution to the exercises using the lab 1 dropbox on the D2L site. Submit only a single text file
(csc242lab1.py) with each of the completed functions and classes for the lab exercises in it. Submissions after the
deadline listed above will be automatically rejected by the system. See the syllabus for the grading policy.
Grading
Each lab exercise is worth 5 points for a total of 10 points. A grading rubric for the lab exercises is available.
