用lis中的单词排序字符串

Question

我想按字串（行）的长度对字串排序，然后按每行的字数在列表中排序。你知道吗

list_of_words = ['hoop t','hot op','tho op','ho op t','phot o']

所以输出是：

hoot t
phot o
hot op
tho op
ho op t

Answer 1

如果我正确地理解了你想要实现的目标，这就可以做到：

list_of_words = ['hoop t','hot op','tho op','ho op t','phot o']

# first sort the words in each string by their length, from longest to shortest
for i, words in enumerate(list_of_words):
    list_of_words[i] = sorted(words.split(), key=len, reverse=True)

# second sort the list by how many words there are in each sublist
list_of_words.sort(key=lambda words: len(words))  # sorts list in-place

# third, join the words in each string back together into a single string
for i, words in enumerate(list_of_words):
    list_of_words[i] = ' '.join(words)

# show results
print(list_of_words)

['hoop t', 'hot op', 'tho op', 'phot o', 'ho op t']
