Help needed with NMVert.co

Hi
I’m improving an importy script that created a lot of doubles. I keep a list of vertexes already created to look up whether it already exists in the mesh:


    v = NMesh.Vert(float(cmd[2]), float(cmd[3]), float(cmd[4]))
    v=transVertex(v,offset,tm)
    vert=v.co
    
    if vert in vList:
       idx1=vList.index(vert)
       print "old vert", idx1
    else:
       aMesh.verts.append(v)
       vList.append(vert)
       idx1=idx
       idx=idx+1

However it never finds a same vertex in the list. Even if every part of the list is the same like [0,0,0] versus [0,0,0]. The NMVert.co does return a list, doesn’t it. When I try the following


if v.co==[0,0,0]:

it gives a run-time message:


attempting vector operation with unsupported type ....

what am I doing wrong here?
Thanx in advance
Alex

Your comparing a listType to a vectorType which is undefined. Try comparing the elements of the vector to int/float values.
