I'm trying to make a grade average system but with while loops, how can I individually get the outputs from the while loop?

Question

This is what I've came up so far:

Is there like a way to individually get the output/answers from the while loop so I can add and divide them? Or is there another way like a for loop to access them? I'm quite new to coding so thanks in advance!

If you're trying to store multiple grades, and perform operations on them, then a list can help. You can define "grades" as a list variable before the while loop. Then after the loop you can use print() function to see what's in the list.

Using a for loop, you can perform operations with each grade in the list. To get the sum of the grades you can define a "sum" variable and add each grade from the for loop.

Based on what you've said, I think this is a good starting point:

EDIT: Changed variable "sum" to "g_sum" because sum is a built-in Python method. Using a variable by the same name could pose a problem if you tried to use this method.

unit = 0
grades = [] # this is the list of grades

while unit < 8:
    # append will add each grade to the list
    grades.append(int(input("Enter Grades: ")))
    unit += 1

# printing all values in the list
print(grades)

# we can already get a denominator from the length of the list
denominator = len(grades)

# for loop to get sum of all grades in list
g_sum = 0
for g in grades:
    g_sum += g

# now we can get the average
average = g_sum / denominator

# printing sum and average of grades
print(f"Sum of grades: {g_sum}\nAverage of grades: {average}")
