在列表列表中分割字符串 [英] Split strings in a list of lists

问题描述

我目前有一个列表列表:

I currently have a list of lists:

[['Hi my name is'],['What are you doing today'],['Would love some help']]

我想在列表中拆分字符串，同时将其保留在当前位置.例如

And I would like to split the strings in the lists, while remaining in their current location. For example

[['Hi','my','name','is']...].. 

我该怎么做?

另外，如果我想在搜索特定列表后使用它，说我搜索正在执行"，然后想在该特定列表中添加一些内容.我该怎么做呢?/p>

Also, if I would like to use a specific of the lists after searching for it, say I search for "Doing", and then want to append something to that specific list.. how would I go about doing that?

推荐答案

您可以使用列表推导来创建包含所有句子的新列表列表:

You can use a list comprehension to create new list of lists with all the sentences split:

[lst[0].split() for lst in list_of_lists]

现在，您可以循环浏览并找到符合条件的列表:

Now you can loop through this and find the list matching a condition:

for sublist in list_of_lists:
    if 'doing' in sublist:
        sublist.append('something')

或不区分大小写地搜索，请使用 any()和生成器表达式；这将是找到匹配项的最少单词数:

or searching case insensitively, use any() and a generator expression; this will the minimum number of words to find a match:

for sublist in list_of_lists:
    if any(w.lower() == 'doing' for w in sublist):
        sublist.append('something')
