If I'm understanding it right, try this:
import itertools
def sort_uvs_by_shells(uvs, shells):
groups = itertools.groupby(sorted(zip(shells, uvs)), key=lambda x: x[0])
return ((group[0], [x[1] for x in group[1]]) for group in groups)
# dictionary version:
# return {group[0]: [x[1] for x in group[1]] for group in groups}
uvs = list(range(16))
shells = [0, 0, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 1]
result = sort_uvs_by_shells(uvs, shells)
for shell, uvs in result:
# dictionary version:
# for shell, uvs in result.iteritems():
print("uvs for shell %d: %s" % (shell, uvs))
