The provided code has two primary issues that need attention:

1. Double Join Operation:

   • The line answer_text = '\n\n'.join('\n\n'.join([a.get('content') for a in answer])) for answer in answer_text_list) contains unnecessary double joins.

2. Handling of List of Lists:

   • Since each element in answer_text_list should be another list itself (i.e., [{'content': 'text'}, {'content': 'text'}]) and you want to join these lists with \n\n, it's simpler to directly flatten the entire list of lists before joining them together without nested joins.

Here’s an optimized version of the code addresses both issues:

With this change, we ensure that each entry from answer_text_list is processed separately without needing nested joins, resulting in more straightforward and efficient handling of multi-level data structures.
