Question

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

Answer 1

#assuming each line has 2 numbers separated by space, and you want the sum of product of these 2 numbers from all the lines
#below code will store that sum in the variable final_line
file_name = input("What is the value-probability file? ")
final_line=0
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_line + final
  
print(final_line)
