####Calculations
##4 We are calculating the total number of classes the student is taking
number_of_classes = (int(credits_taken) / 3)
##5 Calculating the total number of hours student will have to study, per class, to acheive the grade wanted. Assume the same for each class.
if grade_wanted == 'A':
studyhours_needed = 15
elif grade_wanted == 'B':
studyhours_needed = 12
elif grade_wanted == 'C':
studyhours_needed = 9
elif grade_wanted == 'D':
studyhours_needed = 6
else:
grade_wanted == 'F'
studyhours_needed = 0
##6 Calculating the total number of hours the student must study for all classes.
total_number_studyhours_perstudent = (number_of_classes * studyhours_needed)
##7 We are going to display the following information to the user.
print('Name:',first_name + " "+ last_name)
print('Credits:', credits_taken)
print('Study Hours:',total_number_studyhours_perstudent)
print('Grade:', grade_wanted)
##8 Calc the total number of students who used the program.
total_students = total_students + 1
##9 Calc total number of credits taken by all students who used the program.
total_credits = total_credits + int(credits_taken)
# print(total_credits)
#10 Calc total number of study hours for all students who used the program.
allstudents_studyhours = total_number_studyhours_perstudent + allstudents_studyhours
# print(allstudents_studyhours)
#11 This will determine if you would like to keep running the program, or quit.
run_again = input('Would you like to continue using the program? If yes, please enter Y, any other key will exit')
#12 Calculate and display the following information to the user.
print('Total Students:', total_students)
print('Average Credits:', total_credits / total_students)
print('Average Study Hours:', allstudents_studyhours / total_students)
I need this is function format. This question was refused because of name validation--it just has to be letters and a non null value
