Input for grade in a for loop list python [closed]-CodePudding

I have this simple code

students = ['jill', 'bill', 'Gill', 'Fill', 'Dill']
grades = int(input("Enter grade: "))
for student in students:
    print(student, grades)

The output is

Enter grade90
jill 90
bill 90
Gill 90
Fill 90
Dill 90

I want to connect each grade to the name and average them up.

CodePudding user response：

Ask for the grade in the loop. To calculate the average, total all the grades and divide by the number of students.

students = ['jill', 'bill', 'Gill', 'Fill', 'Dill']
total = 0
for student in students:
    grade = int(input(f"Enter grade for {student}: "))
    total  = grade
average = round(total/len(students))
print(f"Average grade is {average}")

CodePudding user response：

You need another list to remember the grades:

students = ['jill', 'bill', 'Gill', 'Fill', 'Dill']
grades = [int(input(f"Enter grade for {student}: ")) for student in students]
for student, grade in zip(students, grades):
    print(student, grade)
print(f"Average: {sum(grades)/len(grades)}")

Or even better, a dict:

students = ['jill', 'bill', 'Gill', 'Fill', 'Dill']
grades = {student: int(input(f"Enter grade for {student}: ")) for student in students}
for student, grade in grades.items():
    print(student, grade)
print(f"Average: {sum(grades.values())/len(grades)}")

Output for both:

Enter grade for jill: 61
Enter grade for bill: 34
Enter grade for Gill: 87
Enter grade for Fill: 94
Enter grade for Dill: 100
jill 61
bill 34
Gill 87
Fill 94
Dill 100
Average: 75.2
