(a,b,c) is a "tuple", not a "vector". IMHO, the "elegant" thing to do is to define a vector class and use it. For convenience, allow a tuple initializer: V = Vector a = V(1,"abc",0.3) + V(2,"def",10.2) Of course, the class "Vector" will have to define math operators appropriately. Note that "%" has the correct precedence to sub for cross-product, and sort of looks like an X if you squint hard enough ;-). -- Terry Hancock ([EMAIL PROTECTED]) Anansi Spaceworks http://www.AnansiSpaceworks.com -- http://mail.python.org/mailman/listinfo/python-list
