how can I get the vertex weight and vertex paint in the BGE?

import bge

cont = bge.logic.getCurrentController()
obj = cont.owner

meshList = obj.meshes
mesh = meshList[0]

for I in range(0,400):
vert = mesh.getVertex(0, I)
print(dir(vert))


does not give you the vert.weight or vert.texpaint, how would I go about accessing either or both of these?
