Python入門基礎：函數與字符串練習

 

函數和字符串的練習：

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.upper()
    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)

print(break_words('hello,world'))
print(sort_words('hello,world'))
print(sort_sentence('abc'))
print(print_last_word('abc'))
