Can anyone please help me with the following please? My question is in a while loop; how do l sum all the numbers in the given list (list_a)? list_a = [8, 5, 2, 4] sum_a = 0 # for storing the sum of list_a i = 0 # for looping through the list_a# Use a while loop to sum all numbers in list_a# If you store the sums into sum_a print(sum_a) # should print 19
