  # Traverse through the address parts
  for index, word in enumerate(address_words):

    # house number or part of the street name

  # Does anything else need to be done
  # before returning the result?

  # Return the formatted string
  return "house number {} on street named {}".format(house_number, street_name)

print(format_address("123 Main Street"))
# Should print: "house number 123 on street named Main Street"

print(format_address("1001 1st Ave"))
# Should print: "house number 1001 on street named 1st Ave"

print(format_address("55 North Center Drive"))
# Should print "house number 55 on street named North Center Drive"
