Loops, summation: Write a function named 1ist_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 [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: [5.01 5.0 Test case 3: 0.0
