Hello, I need help solving this Lab simulation, It uses Sum extra credit for Lists and Dictionary statements and I am very new at python on so I need help solving it. It is very difficult. It is very confusing since the there are multiple inputs and can only code one input in the simulation.

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:

Sum extra: 8 

test_grades = [101, 83, 107, 90]

sum_extra = -999 # Initialize 0 before your loop

''' Your solution goes here '''

print('Sum extra:', sum_extra)
