glob exclude pattern
I have a directory with a bunch of files inside: eee2314
, asd3442
... and eph
.
I want to exclude all files that start with eph
with the glob
function.
How can I do it?
The pattern rules for glob are not regular expressions. Instead, they follow standard Unix path expansion rules. There are only a few special characters: two different wild-cards, and character ranges are supported [from pymotw: glob – Filename pattern matching].
So you can exclude some files with patterns.
For example to exclude manifests files (files starting with _
) with glob, you can use:
files = glob.glob('files_path/[!_]*')
You can deduct sets:
set(glob("*")) - set(glob("eph*"))
You can't exclude patterns with the glob
function, globs only allow for inclusion patterns. Globbing syntax is very limited (even a [!..]
character class must match a character, so it is an inclusion pattern for every character that is not in the class).
You'll have to do your own filtering; a list comprehension usually works nicely here:
files = [fn for fn in glob('somepath/*.txt')
if not os.path.basename(fn).startswith('eph')]
