Hi Thomas,

def string_factory(dic, strs):
  strings_array = []
  for item in dic:

  return strings_array

Your code looks right to me, maybe try to put it into an array an return it. Cheers toby

Edit: I just found our more or less that your array need to be writed like this "strings_array" instead of just stringsarray
