私は「Pythonをハードウェイで学ぶ」から学んでいますが、この特定のコードは私に多くの頭痛の種を与えます。
def break_words(stuff):
"""This function will break up words for us."""

return words

"""Sort the words."""
return sorted(words)

"""Prints the first word after popping it off."""
word = words.pop(0)
print word
def print_last_word(words):
"""Prints the last word after popping it off."""
word = words.pop(-1)
print word
def sort_sentence(sentence):
"""Takes in a full sentence and returns the sorted words."""
words = brea_words(sentence)
return sort_words(words)

"""Prints the first and last words of the sentence."""
words = break_words(sentence)

def print_first_and_last_sorted(sentence):
"""Sorts the words then prints the first and last one."""
words = sort_sentence(sentence)
