Ah-ha. I was appending a list to the list of connectedVerts.
I still need to test it a bit, but I think this gets me what I'm after. Thanks
guys for holding my hand through it.
btw, how are you guys nicely formatting your code? are there no <code> tags?
#=================================
import pymel.core as pm
from itertools import chain
sel = pm.ls(sl=1, fl=True)
connectedVertGroups = {}
vertGroups = {}
for i, vtx in enumerate(sel):
vtxKey = next((key for key, vtx_list in connectedVertGroups.iteritems() if
vtx in vtx_list), None)
connectedVerts = [ vert for vert in vtx.connectedVertices() ]
connectedVerts.append(vtx)
if vtxKey is None:
connectedVertGroups["group_{0}".format(i)] = connectedVerts
vertGroups["group_{0}".format(i)] = vtx
else:
connectedVertList = list( set( connectedVertGroups.get(vtxKey) ) )
connectedVertList = connectedVertList + [ vert for vert in
connectedVerts ]
vertList = list(vertGroups.get(vtxKey))
vertList.append( vtx )
connectedVertGroups[vtxKey] = connectedVertList
vertGroups[vtxKey] = vertList
