Determining if string contains same word more than once using Python?

Question

I have strings with owner names and I need to identify whether they contain a last name twice.

For example, I may have an owner name that reads "BENNETT MCCARL & ARNETTE BENNETT".

I would like to return True if any word is found in the string twice, and False if all words in the string are unique.

Does anyone know how I can do this using Python?

This question has arisen from gis.stackexchange.com/questions/179164/…, and so its terminology needs some work. I'll try to do that now. — PolyGeo

def check(name):
    words = name.split()
    return (len(words) > len(set(words)))

You can split the name into a word list by spaces, and then transform this list into a set. Its length will become shorter after duplicated words has been eliminated.
