根据 Python 中的分隔符拆分和组合文本

Question

我有一个包含字符串的列表列表。在各种正则表达式工作之后，我将我想用作分隔符的内容 @@@ 插入到我的字符串中：

[['@@@this is part one and here is part two and here is part three and heres more and heres more'],
 ['this is part one@@@and here is part two and here is part three and heres more and heres more'],
 ['this is part one and here is part two@@@and here is part three and heres more and heres more']
 ['this is part one and here is part two and here is part three@@@and heres more and heres more']
 ['this is part one and here is part two and here is part three and heres more@@@and heres more']]

现在，我需要想出这个：

[['this is part one'],['and here is part two'],['and here is part three'], ['and heres more'], ['and heres more']]

到目前为止，我的尝试是臃肿的、老掉牙的，而且通常很难看。我发现自己分裂、组合和匹配。谁能就此类问题推荐一些一般性建议，以及使用什么工具来使其易于管理？

编辑请注意！ and heres more 确实在理想输出中出现了两次！

我认为您实际上需要抓取 @@@ 之后的所有字符，直到下一个 and 或字符串结尾。

>>> [[m] for x in l for m in re.findall(r'@@@(.*?)(?=\sand\b|$)', x[0])]
[['this is part one'], ['and here is part two'], ['and here is part three'], ['and heres more'], ['and heres more']]
