[Bf-python] face.edges ?

[jms]

I suppose that you are rather asking  for a edge index in the face data  
because you can do this :

import Blender
mesh = Blender.NMesh.GetRaw("Plane")
for f in mesh.faces:
     print  mesh.faces.index(f)

And it works  in the Blender 2.28  version and in olders ones too
