OK, For a single field I would suggest simplifying it slightly.

*def**remove_duplicate_values*(dict_list, field):

   seen = []


    *for*dic *in*dict_list:           
        *if*dic[field]*in*seen:

         dic[field] = ""

      *else*: seen.append(value)

   *return*dict_list


That way you can still use it for other fields if

necessary and for 'client' simply call it as


items = remove_duplicate_values(items,"client")


To remove dups in multiple fields just call it
repeated times with different field names. (Notice
that your original mail's example removed more
than the client field duplicates!)
