Without that assumption, the same idea applies to the split list.
def split_product_itertools(s):
words = s.split()
product = list(takewhile(allcaps, words))
return ' '.join(product), ' '.join(words[len(product):])
Because these slice rather than index, either works trivially on an
empty description.
print(split_product_itertools("CAPSICUM RED"))
>>>
('CAPSICUM RED', '')
