Testing:


fnmatch.translate('./Testfile [comment] some text.*')

'(?s:\\.\\/Testfile\\ [comment]\\ some\\ text\\..*)\\Z'


fnmatch.translate('./Testfile [comment? some text.*')

'(?s:\\.\\/Testfile\\ \\[comment.\\ some\\ text\\..*)\\Z'

It seems it translates [comments] as a set of valid characters to look
for and doesn't care about the [] characters, which is what breaks it, I
assume.

? translates into RegEx .
* translates into RegEx .*

And escaping doesn't work either, because:


https://docs.python.org/3/library/glob.html#glob.escape demonstrates a 
way of escaping that works:


glob('./Testfile [[]comment]*')




fnmatch.translate('./Testfile [comment\] some text.*')

'(?s:\\.\\/Testfile\\ [comment]\\ some\\ text\\..*)\\Z'

...the \ is replaced with \\ which breaks the pattern since it is no
longer a real escape character but an escaped escape character, if that
makes sense.

When the file name has a non working RegEx set, e.g., './Testfile
comment]*' it works.

Yes, easy to say "don't write that into file names," but I don't make the
rules.

I guess I have to write my own.

Oh, well...

And some of us are just senior citizen tinkerers, like me :) I lurk here, 
hoping some of it will rub into me.

I may qualify as experienced with Python, that being said, "to class
or not to class?" is still an open question.
I have been working on some stuff using Scheme and no OO machinery and
it worked well. Also, mocked
some stuff in the frontend using a purely functional approach. It works.

So, I am wondering what's the purpose of OOP?

Class-based error handling with exception and inheritance is very
handy maybe perfect.

I have been burned by Django class everywhere (ORM, REST, admin UI,
data validation, etc?).

Another place where class shines is when you have the same interface
for different objects.
Like others have said, it's more "duck typing" than OOP. Again
following the "common interface"
an abstract class is helpful and in this case, inheritance makes
sense. But that doesn't require
more that one or two level deep inheritance.

So, in the end, I think that except for error handling and the
subject.verb(**complements) syntax. OOP is dubious.

Multiple inheritances outside mixin anyone? Metaclass outside ORM / ODM?

Understood. Now I know why the error is stuck on that line.
This gives me a clue.
