Question

Many classes calculate a final grade by using a weighted scoring system. For example, “Assignments” might be worth 40% of your final grade. To calculate the grade for the Assignments category, the teacher takes the percentage earned on the assignments and multiplies it by the weight. So if the student earned a 90% total on the Assignments, the teacher would take 90% x 40, which means the student earned a 36 percent on the Assignments section. The teacher then calculates the grade in the other categories (Quizzes, Midterm Exam, Final Exam, etc.) and sums the grades earned in each to come up with the Final Score, and assigns a letter grade based on that score.

Write Python pseudocode that allows the teacher to calculate the grade for a student. The teacher will first enter the Student ID number, first name, and last name. This information will be followed by entering in the score for each of the following categories: Assignments, Quizzes, Midterm Exam, & Final Exam

The weights for each category are as follows:

Assignments - 50%
Quizzes – 15%
Midterm – 15%
Final – 20%

Once you have the scores for each individual category, calculate a total score for the course. Then assign a letter grade to the student based on the following grade scale:

90 – 100 = A
80 – 90 = B
70 – 80 = C
60 – 70 = D
< 60 = E

Print the results in exactly the following format:

[Last Name], [First Name]
Student ID: [Student ID]
Assignments: [Assignment Score]
Quizzes: [Quizzes Score]
Midterm: [Midterm Score]
Final: [Final Score]
Total Score: [Total Score]             Grade: [Letter Grade]

Then ask the user if they would like to enter another student or quit. Continue the process until the user chooses to quit.

Answer 1

The code is commented for understanding

CODE:

# Weight of the exams
assign_weight = .5
quiz_weight = .15
mid_weight = .15
finals_weight = .2

repeat = 'y'

while(repeat == 'y'):
# Take user input
sid = input('Student Id: ')
first = input('First Name: ')
last = input('Last Name: ')
assign = float(input('Assignment Score: '))
quiz = float(input('Quizzes Score: '))
mid = float(input('Midterm Exam Score: '))
finals = float(input('Final Exam Score: '))

# Calculate total score
score = assign * assign_weight + quiz * quiz_weight + mid * mid_weight + finals * finals_weight

# Calculate grade
grade = None
if score > 90:
grade = 'A'
elif score <= 90 and score > 80:
grade = 'B'
elif score <= 80 and score > 70:
grade = 'C'
elif score <= 70 and score > 60:
grade = 'D'
else:
grade = 'E'

print(last, first, sep=", ")
print("Student ID: ", sid)
print("Assignments: ", assign)
print("Quizzes: ", quiz)
print("Midterm: ", mid)
print("Final: ", finals)
print("Total Score: ", score, '\t', "Grade: ", grade)

# Take user input to repeat the score calculation
repeat = input('Do you want to enter another student (y/n)')
if(repeat == 'y' or repeat == 'Y'):
continue
else:
break
