Is there a command or module that I can use to add all the items in a list?
Alternatively, is there one I can use to add all the numbers in a file?

Hello Jerry,
Tricky solution using minidom (standard) Not tested:
import ElementTree
import minidom
def prettyPrint(element):
txt = ElementTree.tostring(element)

Correct, but it is not limited to lists. Any itterable with
ints/floats will do, for example a tuple is also accepted.

Yes, that is the first place I went looking, but I couldn't find such a class.
I found one project using numpy for geometry objects (geometry-simple,
http://code.google.com/p/geometry-simple/), but
I am happier with this:
class PointND(list, object):
def __init__(self, *a_list):
super(PointND, self).__init__(a_list)
self.maxIndex = len(self) - 1
def getSet(ix, attName):

attName)
