C Python MIS 315 – Fall 2022. Programming Assignment #2. Objectives: Functions, Lists, lists of lists This program and the next program work together. I cannot accept assignments after the deadline, as I will provide the key needed to work on programming assignment #3 Grading: 1. 10 2. 5 3. 10 (this is a B) 4. 5 QUESTION 1.Build a list of lists called studGrades, using the data in file DATA_PROJ2.txt, shown in canvas files. For reference, I use the words “table”, “row”, and “column” for the”2 dimensional” list studGrades. Each row contains the data for one student, and it will be used to compute the final letter grade of the student. Data of one row are the following Column 0: unique student id (a number) Col 1: “L” for the usual letter grading (A, B, …) , ”Cr” for Credit/noCr Col 2: major – col 3: transfer student? -Col 4 -year Col 5: gpa – col6 project 1 grade –Col 7 project 2 grade Col 8: exam 1 grade – col 9: exam2 grade To build the table studGrades in the Python program, copy and paste one row at a time from the file DATA_PROJ2.txt into the table studGrades (again, “table” is not a standard Python keyword, I use it to represent a list of lists or 2-dimensional list). Insert commas and “[“ and “]” where needed to make studGrades a correct list of lists (Murach top of page 179) This table MUST be in main() Print table studGrades, showing one row per line QUESTION 2.Compute the average gpa. Compute how many students have their gpa greater than the average gpa. PRINT both results from main() You must use a function for this question, besides main(). The table studGrades must be a parameter of this function (not a global variable). Both results must be returned to the calling program ( main()) using a “return” statement and printed from main() QUESTION 3. For each student, compute the final project grade based on the combination of grades for project 1 (col 6) and grade for project 2 (col 7) as follows(3 steps) First step newProj1grade = project1Weightproject1_grade newProj2grade= project2Weightproject2_grade Use : project1Weight = 2 project2Weight = 1.5 .Those are “global constants” (Murach, page 114, 115, names of the constants should be in upper-case) All rows have the same project1Weight. All rows have the same project2Weight REMARK. I am not always respecting Python syntax and consistent in the use of variable names in this text. The names I use are descriptive of the data they hold, but you need to choose the variable names for your program .Second step calculate: projgrade = newProj1grade+ newProj2grade Third, insert the value of projgrade at column 8 of studGrades for each row. (note: insert, not append) You must use a new function for this question Print the following from main(): rows for student id 1111, 4555, 9500 with columns 0, 6, 7, 8, 9, 10 QUESTION 4. For each student, compute the final exam grade based on the combination of grades for exam1 (col 9) and grade for exam 2 (col 10) as follows. First, compute firstKmod as follows: Kmod = 1.2 for juniors who are not transfer students (col 3), Is 1.4 for juniors who are transfer from CC, is 1.5 for other juniors, is 2 for sophomores or seniors and grading type “L” (col 1), 2.5 for sophomores with grading type Cr, 1 for all other students Then newExam1grade = Exam1WeightExam1_grade newExam2 grade= Exam2WeightKmod*Exam2_grade All students have the same Exam1Weight = 3 (global constant) All students have the same exam2Weight=5 (global constant For each student, compute examgrade = new Exam1grade+ new Exam2grade; append Print the following from main(): rows for student id 1111, 4555, 9500 with columns 0, 9, 10, 11 You must use a new function for this question.
