Those lines with multiple numbers (e.g. "39 40 30") - do you want to add 39,
40, and 30 to the list, or "39 40 30"?
If you want to add the whole line as a unit, then just read each line,
split() at the #, strip() the first part, and add it to the list.
If you want them to be separate numbers, then read each line, split() at the
#, split() the first part by spaces, and add each item to the list.
