12 12 34 56 12 45

1 34.4 1 234.1 0 0 3

0 0 1 3 4 5 1 2

123

Step 2:

Write a program that reads each line of data and displays the sum of each line.

2.Open that file

a.For each line in the file

i.Convert it to a list of numbers

ii.Sum all the numbers in the list

iii.Print the total and the average of those numbers

3.Close the file

Make sure it ignores lines that begin with "#" or that have a length of zero. If the file does not exist dont crash. Just tell the user that it doesnt exist.
