Get vertex's assigned material?

Im stuck on this for a while now. In blender it’s possible to assign a material to specific vertices.
(edit mode -> select vertice -> select material slot -> click assign button).

However I can’t figure out how to retrieve this information via python.

I have however found out:
How to find the materials assigned to a mesh.

bpy.meshes[0].materials

How to find the material assigned to a face

bpy.data.meshes[0].faces[0].material_index

But how to find the material assigned to a vertex? I’m lost. Please help!

[edit] Blender version is 2.62

Solution As it turns out, it’s impossible to assing materials to vertices, you can just assign them to faces. This explains why this is the only data available throught the python API.
My bad, i guess. :smiley:
