我的正则表达式没有在字符范围内明确包含破折号，但是当输入文件名如下时，我的代码会失败：
Rage Against The Machine - 1996 - Bulls On Parade [Maxi-Single]
这是我的代码：
def find_cue_files(path):
found_files = []
for root, dirs, files in os.walk(path):
if files:
fcue = glob(os.path.join(root, '*.[Cc][Uu][Ee]')) # this is line 81 in my source file (mentioned in the traceback)
# do a few other things...
return found_files
很明显，文件名的这一部分是问题所在：[Maxi-Single]
如何处理与此类似的文件名，以便将它们视为固定字符串，而不是正则表达式的一部分？
（不是我的主要问题，但如果它是相关的，我愿意尝试另一种方法来进行不区分大小写的搜索。我已经查看了关于该主题的几个 Stack Overflow 问题，但我没有 - 到目前为止 - - 找到任何似乎适合这种情况的解决方案。）
这是我的错误：

它处理了早期的文件名，但现在失败，输入文件名Aerosmith - Aerosmith (2014) [24-96 HD]在我修改后的代码的同一点产生了相同的错误。
