I tried to run the demo on Mac and got a error, how can I fix it?

from polyglot.text import Text, Word

words = ["preprocessing", "processor", "invaluable", "thankful", "crossed"]
for w in words:
  w = Word(w, language="en")
  print("{:<20}{}".format(w, w.morphemes))

and got the error as

  File "de_word.py", line 6, in <module>
    print("{:<20}{}".format(w, w.morphemes))
