Thanks, Nick.
This slight variation on my first groupby try seems to work for
the test data.
def prod_desc(s):
prod = []
desc = []
for k, g in itertools.groupby(s.split(),
key=lambda w: any(c.islower() for c in w)):
if prod or k:
desc.extend(g)
else:
prod.extend(g)
return [' '.join(prod), ' '.join(desc)]
