I'm trying to get the extra credit on an assignment and ran into an issue with the 3rd line from the bottom returning with an error! I need it to print out the assignment average grade code is below:
def print_report(students, num_of_assignments):
# Prints Scores
print("\nFinal grade report:")
for student_id, student_info in students.items():
print(f"{student_info['Name']}'s average score was {student_info['Average']:.1f}, letter grade of {student_info['Letter_Grade']}")
# Calculates and prints the average score for each student (Extra Credit)
print("\nAssignment averages: ")
for i in range(num_of_assignments):
assignment_averages = sum(student_info["Scores"][i] for student_info in students.values()) / len(students)
for i, avg_score in assignment_averages:
print(f"The average for assignment {i} was {avg_score:.1f}, letter grade of {get_letter_grade(avg_score)}")
I know its something with the list function clashing with a dictionary but need help!
Change the bottom bottom portion of code to this:
# Calculates and prints the average score for each assignment (Extra Credit)
print("\nAssignment averages: ")
for i in range(num_of_assignments):
assignment_scores = [student_info["Scores"][i] for student_info in students.values()]
avg_score = sum(assignment_scores) / len(students)
print(f"The average for assignment {i + 1} was {avg_score:.1f}, letter grade of {get_letter_grade(avg_score)}")
The issue was with how you where assigning assignment_scores. It was not wrapped in an array/list to be run in the sum function.
When in doubt, break it out! A few more lines for better code readability is always going to be better than a short, difficult to understand program.
