Welcome to DS2000 CS Practicum 6!
Before we get to the actual exercise let's do a recap of for loops. Complete the quizes below, and we'll discuss the answers immediately in class. Please do one at a time (you have 5 minutes for each), wait for the discussion and only do the next one when everybody is ready!
Exercise 1 and only: Evaluating grades
Scenario: Imagine a class of students,
STUDENT_LIST. Each got grades for two exams, and the grades are held as lists
GRADES_EX_2, like this:
STUDENT_LIST = ['student_10', 'student_56', 'student_02', 'student_03',\ 'student_24', 'student_98', 'student_86', 'student_43',\ 'student_00', 'student_12', 'student_01', 'student_99'] GRADES_EX_1 = [91, 82, 41, 54, 67, 79, 49, 32, 95, 81, 77, 89] GRADES_EX_2 = [55, 82, 47, 22, 67, 36, 99, 51, 53, 66, 90, 91]
All the lists are ordered in the same way, so that
91 in exam 1 and
55 in exam 2, so their GPA is now 73. In this exercise we want to find out:
how many students are in the class,
what the average score was,
what the difference between the highest and the lowest score was,
who got the highest score,
how many passed each exam vs failed one vs failed both
Extra challenge (will help a lot with homework): if the person who has the highest average score is scored max in any of the three exams (yes, suddenly there's a third exam!).
utils.py, try completing them so that
test.pyexecutes successfuly! that's exactly how! for i in range(len(student_list)): gpa = 0 for grade_list in grade_lists: gpa += grade_list[i] gpa = gpa / len(grade_lists) gpa_list.append(gpa)
