DAT 210 Week 2 Using Loops in Python

4. You recently graduated college and you are applying for a programming
job that requires the understanding of loops in Python. The manager you
are interviewing with has asked you to take an assessment to prove your
programming knowledge. Below are the requirements for the
programming skills test.
Create a program in Python that meets the following requirements:
• Creates a list of 10 integers
• Replaces the last entry in the list with one input by the user
• Performs one of the following scenarios (you will be assigned
one in class in week 1):
• Scenario 1: Calculate and print the sum of the list items
• Scenario 2: Find and print the minimum item in the list
• Scenario 3: Find an item matching the one input by the user or
print not found

5. • Include a program header with your name, date, assigned
scenario #, and program purpose.
• You may use JDoodle, another online code editor, or your
desktop install of Python.
Provide the actual code as a Python script (".py") and also take a
screenshot of the output, then paste the screenshot(s) into a Microsoft®
Word document. Your submission should then include two items: the
script and the Word document. Include your name and week # in both
file names.
Review Chapters 6 and 11 of Python for Everyone if you have additional
questions on creating a program in Python.
Submit your document.
Submissions that duplicate the submission of another student

DAT 210 Week 3 Control Structures

11. You work for a software company has just created a new incentive for
salespeople to earn a commission on each sale. The current program
only allows for a fixed salary. The Chief Information Officer (CIO) has
asked you to create a new program that allows the functionality for a
fixed salary and commission.
Write a Java® application, using NetBeans IDE, that calculates the total
annual compensation of a salesperson.
Consider the following:
• A salesperson will earn a fixed salary of $30,000.
• A salesperson will also receive a commission as a sales
incentive. Commission is a percentage of the salesperson's annual sales.
The current commission is 7% of total sales.
• The total annual compensation is the fixed salary plus the
commission earned.
The Java® application should meet the following technical
requirements:

12. • The application should have at least one class, in addition to the
application's controlling class. (A controlling class is where the main
function resides).
• A file needs to be created to contain the output.
• There should be proper documentation in the source code.
• The application should ask the user to enter annual sales, and it
should display the total annual compensation.
Compile your Java® application files into a ZIP folder.
Review the Lynda.com® videos from this week if you have additional
questions on creating a program in Java®.
Submit the ZIP file.

DAT 210 Week 4 Write a Ruby Program

15. The college IT department manager no longer wants to use spreadsheets
to calculate grades. The manager has asked you to create a program that
will input the teachers' files and output the students' grades.
Write a Ruby program named format file.rb, which can be run by typing
ruby widgets.rb.
In your Ruby environment, the program must read an input file
formatted in CSV format, named input.csv. Each record contains data
about a student and their corresponding grades.
The data will look similar to the following:
Student Name, assignment 1, assignment 2, assignment 3, assignment 4
John Adams, 90, 91, 99, 98
Paul Newman, 90, 92, 93, 94
Mary Smith, 95, 96, 99
Be careful to follow the output format exactly, including spacing. The
output of your program must look like the following:

16. Student Assignment Average
John Adams 94.5
Compress your files into a ZIP folder.
