Restructure the main function so that its code looks as follows: 1 def print_score(name, value): # ... 2 3 4 def calculate_grade (project, exam): 5 # ... 6 7 # ADD MISSING FUNCTIONS 8 9 10 11 def main(): project_score = read_number('Enter project score:') exam_score = read_number('Enter exam score:') grade = calculate_grade (project_score, exam_score) print_report(project_score, exam_score, grade) 12 13 14 15 main() The external behavior of the code should remain as before. ? You need to add functions read_number and print_report
