Let's see what was causing the error:

> good_data = a + "," + line[:6] + "," + line[-13:]

This actually looks almost right --- you need to make sure that when
you're doing string concatenation that all of things you're adding up are
strings.  Since 'a' is defined as:

  a = ['08/18/00']

this explains that "TypeError" --- 'a' is not a string, but a
list.  However, the first item in a, a[0], is a string.

  good_data = a[0] + "," + line[:6] + "," + line[-13:]

will work.  It looks awkward to have a list with one item, unless you
really wanted that.  If not, it's simplest just to say:

  a = '08/18/00'

Also, the date is not Y2K compliant, so you might want

  a = '08/18/2000'

instead.  *grin*

Good luck!
