Assign sum_extra with the total extra credit received given list test_grades. Iterate through the list with for grade in test_grades:. The code uses the Python split() method to split a string at each space into a list of string values and the map() function to convert each string value to an integer. Full credit is 100, so anything over 100 is extra credit. Sample output for the given program with input: '101 83 107 90'Sum extra: 8(because 1 + 0 + 7 + 0 is 8)user_input = input()test_grades = list(map(int, user_input. split())) # test_grades is an integer list of test scoressum_extra = 0 # Initialize 0 before your loop''' Your solution goes here '''print('Sum extra:', sum_extra)
