[Visualpython-users] vectors and lists

[Joe H. <hea...@gm...>]

I can type
locations = [vector(-6e-11,0,6e-11),vector(-6e-11,-6e-11,0),\
             vector(-6e-11,6e-11,0),vector(-6e-11,0,-6e-11)]

and

locations.append(vector(-6e-11,0,6e-11))
locations.append(vector(-6e-11,-6e-11,0))
locations.append(vector(-6e-11,6e-11,0))
locations.append(vector(-6e-11,0,-6e-11))

but I get an index out of range error when I type

locations[0] = vector(-6e-11,0,6e-11)
locations[1] = vector(-6e-11,-6e-11,0)
locations[2] = vector(-6e-11,6e-11,0)
locations[3] = vector(-6e-11,0,-6e-11)

Does Visual change the initial index or is something else going on?

I can't reproduce that.  Things work as expected for me.
(WinXP, visual 3.2.10, python 2.5.1)

try len(locations)

what happens if you simply try to display locations[0] or locations[3], etc ?
