السلام عليكم ورحمه الله وبركاته . .

عندي مشكلة في هذا الكود المكتوب بالبايثون , خطأ في السطر الرابع . .

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

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

def print_first_word(words):
    """Prints the first word after popping it off."""
    word = words.php(0)
    print word

def sort_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 prinits the first and last one."""
    words = sort_sentence(sentence)
    print_first_word(words)
    print_last_word(words)
