I'm trying to handle a bunch of files, and I need to alter then to remove extraneous information in the filenames; notably, I'm trying to remove text inside parentheses. For example:

filename = "Example_file_(extra_descriptor).ext"

and I want to regex a whole bunch of files where the parenthetical expression might be in the middle or at the end, and of variable length.

What would the regex look like? Perl or Python syntax would be preferred.

s/\([^)]*\)//

So in Python, you'd do:

re.sub(r'\([^)]*\)', '', filename)
