我的正则表达式没有显式地在字符范围内包含破折号，但是当输入文件名如下时，我的代码失败了:
Rage Against The Machine - 1996 - Bulls On Parade [Maxi-Single]
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]
如何处理类似的文件名，使它们被视为固定字符串，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。我已经看了几个关于这个主题的堆栈溢出问题，到目前为止，我没有找到任何适合这种情况的解决方案。
这是我的错误:

它处理了先前的文件名，但现在失败了，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相同的错误。
与其对通过根传递的奇怪文件模式使用glob，不如只对名称进行排序，然后在根之前加上名称。一个可能的单行代码:
fcue=list(map(lambda x: os.path.join(root,x), (f for f in files if f.lower().endswith('.cue'))))
