If tokens are separated by whitespace (only and not commas), you
can use the ":tokens" suffix to request variables (described e.g. in

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

).

If you need "," as well as separator, you must tokenize yourself.
If "," alone is used as separator, the string method "split" is adequate maybe
in connection with "strip" (to remove whitespace at the ends).
