Python LPTHW EX25,我认为有';我的powershell有什么问题吗?即使复制和粘贴

Python LPTHW EX25,我认为有';我的powershell有什么问题吗?即使复制和粘贴,python,Python,所以将其复制到一个名为ex25.py的文件中- def break_words(stuff): """This function will break up words for us.""" words = stuff.split(' ') return words def sort_words(words): """Sorts the words.""" return sorted(words) def print_first_word(words)

所以将其复制到一个名为ex25.py的文件中-

def break_words(stuff):
    """This function will break up words for us."""
    words = stuff.split(' ')
    return words

def sort_words(words):
    """Sorts the words."""
    return sorted(words)

def print_first_word(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 = break_words(sentence)
    return sort_words(words)

def print_first_and_last(sentence):
    """Prints the first and last words of the sentence."""
    words = break_words(sentence)
    print_first_word(words)
    print_last_word(words)

def print_first_and_last_sorted(sentence):
    """Sorts the words then prints the first and last one."""
    words = sort_sentence(sentence)
    print_first_word(words)
    print_last_word(words)
现在在Blueshell中,将cd复制到文件夹所在的位置,键入“Python”激活Python,然后从Zed的网站复制/粘贴此代码-

import ex25
sentence = "All good things come to those who wait."
words = ex25.break_words(sentence)
words
sorted_words = ex25.sort_words(words)
sorted_words
ex25.print_first_word(words)
ex25.print_last_word(words)
words
ex25.print_first_word(sorted_words)
ex25.print_last_word(sorted_words)
sorted_words
sorted_words = ex25.sort_sentence(sentence)
sorted_words
ex25.print_first_and_last(sentence)
ex25.print_first_and_last_sorted(sentence)
结果(我的问题)-

尝试
dir(ex25)
浏览模块,并确保
已排序的单词
仅在返回的单词中,没有有趣的额外字符,等等。。。
