Python 3.x 删除前缀和后缀，同时保留python

你好，我想清理我的数据文件 并希望： 删除前缀为“[”或后缀为“]”的单词，但保留这些单词 三个符号：[/]、[/]和[*]

我的示例文本与我阅读的文件相同：

有一个男孩在罐子里放了一只青蛙。第二天早上，男孩和狗在睡觉。第二天早上，男孩和狗在睡觉他们开始到处寻找它。\n'，“\t[/-]它不在他的房间里。\n'，“\t他在外面叫它来。\n'，“\t狗失去了抓窗户和窗台的能力，掉了下来，\n']

我尝试过使用startswith和endswith，但我似乎无法保留符号

clean=[“”.join（y表示x.split（“”）中的y，如果不是y.startswith（前缀）或y.endswith（后缀））不是“[/]”、“[/]”和“[*]”表示文本中的x]

（很抱歉，我的代码很糟糕，试图整理我的想法）

请发布一些您尝试过的代码以及预期输出和实际输出。但是，请参见Python3.9，我认为这可能是一个X/Y问题。你能展示一下你目前正在使用的代码吗，这样我们就能更好地帮助你了？只是添加了我的代码，不工作，但在那里练习我的方法taken@jixubi请添加所有相关代码。比如，你如何得到你在列表理解中循环的
