In this section of python programming, we will understand the python code to print the cumulative sum of the elements in the list. The ith element of the new list is the sum of (ith + 1) element.
input_list = [ 2, 2, 3, 5, 4, 3] sum = 0 new_list =  length = len(input_list) upd_list =  for i in range(length): sum = sum + input_list[i] upd_list.append(sum) print("Cumulative list:",upd_list)
In the above python code, we have created a list with elements. The for loop will iterate over the length of the list and calculates the arithmetic sum each time the value is traversed and appended to the updated list which we have created. When all the elements are traversed and the control comes out of for loop, the updated list of cumulative sum is printed on the screen
