將拆分后的句子切片[-2:]將返回所需的輸出。嘗試：
sentence = "Hello world, there is 200 pcs"
what_I_need = sentence.split()
print(what_I_need[-2:]) # output: ['200', 'pcs']
# or as a string:
print(" ".join(what_I_need[-2:])) # output: 200 pcs

def get_last_n_words(n:int, sentence:string):
last_n_Words = ' '.join(sentence.split()[-n:])
return last_n_words
sentence = "Hello world, there is 200 pcs"
lastThreeWords = get_last_n_words(3, sentence)
# lasthreeWords: "is 200 pcs"
