1. Look at the csv module.  It makes dealing with csv very convenient.
2. The fact that every other line in your input file is blank will
require you to through out those lines.  One way to do this is with
slicing:
    >>> a = [0,1,2,3,4,5,6]
    >>> b = a[::2]
    >>> b
    [0, 2, 4, 6]
    >>>
3. I would read the input into a list of lists (each line item is in a
list, each line is in the containing list
4. get rid of the blanks
5. make a function to take the input lists and do your math,
producting a list of lists to be output
6. use the csv writer to write to a file
7. You have way to many comments in your code.  At the top of your
file, and immediately underneath each function definition use
docstrings (triple quoted multi-line strings).  These are great in
that they provide automatic documentation for your functions using
pydocs, or when you are in the python shell you can do
help(function_name) and find out what it does
