最近在學(xué)習(xí)python,其中遇到一道習(xí)題是改錯(cuò)的。
原代碼如下
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)
他要求的輸出如下:
$ python

>>> import ex25

>>> sorted_words = ex25.sort_words(words)
>>> sorted_words

wait.

All
who
>>> ^D

求高人幫我改改原輸入代碼,像上面輸出給我的感覺是他是不是在IDLE寫的?還有我用文本txt的方式編寫,然后通過python在cmd中運(yùn)行的,最好能改成這種。
