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. Iterate through the map with: for grade in test_grades. Sample output for the given program with input: '101 83 107 90'

Sum extra: 8 

(because 1 + 0 + 7 + 0 is 8)

sum_extra = -999 # Initialize 0 before your loop
