Write a function named list_sum that takes a list of values as input and returns the sum of all the values. For example, if the input is [3,5.0, 9] the function must return 17.0. Return 0.0 if the list is empty. You are not allowed to use the built-in function sum. You can assume that the input list contains only either float or int objects. print ("Test case 1: [4.25, 5.0, 10.75]") ans list sum ([4.25, 5.0, 10.75]) print (ans) print ("Test case 2: [5.0]") ans list_sum ([5.0]) print (ans) print ("Test case 3: []") ans list sum ([]) print (ans) The output should be: Test case 1: [4.25,5.0, 10.75] 20.0 Test case 2: [5.0] 5.0 Test case 3: [] 0.0 Ac 48 Gol
