Program 1: GPA Calculator
- Due Date: Friday, January 26th no later than 11:59 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: Upload your solution, entitled
YourFirstName-YourLastName-PartnerFirstName-PartnerLastName-Program1.py to the BrightSpace Program 1 Dropbox.
If you work with a partner, only one person should submit the solution.
However, to make the recording of grades easier, write both names
in the BrightSpace Dropbox comment box.
- 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
- At Montana State University, the following grades have
the following values:
A (4.0), A- (3.7), B+ (3.3), B (3.0), B- (2.7), C+ (2.3),
C (2.0), C- (1.7), D+ (1.3), D (1.0) and F (0.0).
- Example GPA Calculation: If a student earns an A in a 3 credit course
and a B- in a 2 credit course, that student's GPA can be
calculated as (4.0 * 3 + 2.7 * 2) / (3 + 2).
- Write a Python program that prompts the user for the
number of classes taken and then for each class, the letter grade
received (e.g. B+) and the number of credits (e.g. 3). Once this
information is known, the program should calculate
and display the GPA.
- Here is a sample transcript. Your
solution should match the output format exactly.
- The user will take at least one and no more than seven courses.
- Each course has a credit value between one and five (inclusive).
- A grade can be entered in uppercase or lowercase.
For example, either A- or a-.
- All user inputs will be valid.
Grading - 100 points
- 35 points - The GPA calculation is correct.
- 15 points - The user is prompted to enter the number of courses
(5 points), the letter grade for each course (5 points) and
the credits for each course (5 points).
- 10 points - With the exception of the GPA, the output
format matches the output format of the transcript exactly
(2 points for each type of difference up to 10 points).
- 5 points - The GPA is displayed with two digits to the
right of the decimal.
- 10 points - A function named translate is defined that
takes a letter grade (e.g. b- or B-) and correctly returns its value
- 10 points - A function named main is defined (5 points).
The only python statement that does not appear in this function
or the translate function is the call to the main function,
e.g. main() (5 points).
- 10 points - The Python solution is easy to understand and does
not contain unnecessary code (2 points for each
type of improvement up to 10 points).
- 5 points - An appropriate Python comment appears at the top of
the submission. See below for the type of information that
