空格分隔列表中的字符串
<div>假设我有以下结构：</div><div></div><div>t = [['I will','take','care'],['I know','what','to','do']]</div><div>
</div><div>正如您在第一个列表中看到的，我有 'I will' 并希望它们分成两个元素 'I' 和 'will' ，结果是：</div><div>
</div><div>[['I', 'will', 'take', 'care'], ['I', 'know', 'what', 'to', 'do']]</div><div>
</div>快速脏算法如下：new = []
for sent in t:
new = []
for word in sent:
temp = word.split(' ')
for item2 in temp:
new.append(item2)
train_text_new.append(new)
但我想知道是否有更易读、更有效的算法来解决这个问题。
回答
您可以制作一个简单的生成器来生成拆分，然后在列表推导中使用它：
t = [['I will','take','care'],['I know','what','to','do']]
def splitWords(l):
for words in l:
yield from words.split()
# [['I', 'will', 'take', 'care'], ['I', 'know', 'what', 'you', 'to', 'do']]
