In python: Assign sum_extra with the total extra credit received given list test_grades. Full credit is 100, so anything over 100 is extra credit. For the given program, sum_extra is 8 because 1 + 0 + 7 + 0 is 8.

Sample output for the given program with input: '101 83 107 90'

Sum extra: 8

Following are the code to this question:

list_val = input()#defining a integer variable for input value

test_grades = list(map(int, list_val.split()))#defining test_grades as a list

sum_extra = -999 #defining sum_extra that holds negative integer value

sum_extra = 0#defining sum_extra that holds value

for y in range(len(test_grades)):#defining a for loop to check range of list  

   if(test_grades[y] > 100):# defining if block that check list value is greater then 100

       sum_extra = sum_extra + (test_grades[y] - 100)#use sum_extra variable to hold extra value and add this value

print('Sum extra:', sum_extra)#print value

Output:

101 83 107 90

Sum extra: 8

Explanation:

In the above code a, "list_val" variable is declared, that uses an input method to input the values and declared a "test_grades" variable that uses a list method to add all values in the list.

In the next step, the "sum_extra" variable is declared, which holds some values and defines a for loop to check the range of the "test_grades", and define a if block, that checks list value is greater than 100. If the condition is true, it will remove the extra value, and add it into the sum_extera variable and add its value, and at the last use, print variable to print its value.
