For slightly more complex option text, you can use the CSV module to
do the heavy lifting, so if you have something like

  [section]
  option="one, one, one",two,3

then you can have Python give you

  my_list = next(csv.reader([cp.get("section", "option")]))

or alternatively use the shlex module and separate them like shell
options:

  [section]
  option="one, one, one" two 3

then do

  my_list = list(shlex.shlex(cp.get("section", "option")))

Or yet one more way using Python list syntax for literals:

  [section]
  option=["one, one, one", "two", 3]

and get them with

  my_list = ast.literal_eval(cp.get("section", "option))

Lots of fun (and batteries-included) ways depending on how you want
to represent the list in the config file and what sorts of data it
can contain.
