I need help to calculate the sum of this, i just don't know how......

file_name = input("What is the value-probability file? ")

with open(file_name , "r") as final:

for numbers in final:

split_function = numbers.split()

num_one = float(split_function[0])

num_two = float(split_function[1])

final = num_one * num_two

final_line = final

So when my code runs the output looks like this :

What is the value-probability file? hw3_part2_test1.txt -0.567032 -17.630715000000002 3.194056 4.398823 13.990935

I need all these numbers now to add to the next line and next line and give me sum..

I need the output answer to be : 3.386066999999997
