Revit API python Error:Exception: idx can be only 0, 1, 2

Can someone help me understand this error. I'm still learning the Revit API (and python) and searching hasn't helped. I'm trying to get the xyz Location Point of an element.

here is my code:

elements= ui.Selection() 
for d in elements:
for l in d.Parameters:
    for x in d.Location.Point:
        print x

here is the output, NOTE: it does return three values:

149.412934765
69.7704247908
-3.71628688979

here is the error message. I don't understand the reference to idx in the error message:

IronPython Traceback:

A Point is not an array of values, accessing X, Y, Z is the right way.

While I still do not understand the error, I was able to eliminate the error message by editing my code as follows:

elements= ui.Selection() 
for d in elements:
for l in d.Parameters:
    for pt in d.Location.Point:
        print pt.X
        print pt.Y
        print pt.Z
