Question

I'm using python, and I'm not sure how to print this Your total is 22 out of 30, or 73.33%Also, how can i use the for loop on this-

  1. Write an algorithm that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by each of the N scores and totals.  Calcuate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage.  Sample input and output is shown below:

How many exercises to input? 3

Score received for exercise 1: 10

Total points possible for exercise 1: 10

Score received for exercise 2: 7

Total points possible for exercise 2: 12

Score received for exercise 3: 5

Total points possible for exercise 3: 8

Your total is 22 out of 30, or 73.33%

This is what I have:

possScores = 0
sumOfScores = 0
totalScores = 0


numOfExer = int(input("How many exercises to input? "))

# Taking number 1 from user as int
exer1 = int(input("Score received for exercise 1: "))

possScores1 = int(input("Total points possible for exercise 1: "))
 
# Taking number 2 from user as int
exer2 = int(input("Score received for exercise 2: "))

possScores2 = int(input("Total points possible for exercise 2: "))
# Taking number 3 from user as int
exer3 = int(input("Score received for exercise 3: "))

possScores3 = int(input("Total points possible for exercise 3: "))
 
# adding num1 and num2 and storing them in
# variable addition
sumOfScores = exer1 + exer2 + exer3
possScores = possScores1 +  possScores2 + possScores3
totalScores = sumOfScores/possScores
 
# printing
print("Your total is ", sumOfScores,"out of ",possScores, "or ")
