Question

In many python scripts I find my self doing the following:

for maybe_glob in sys.argv[1:]:
    for filename in glob.iglob(maybe_glob):
        print(filename)

I have to do this because the scripts need to also run in terminals that do not expand wildcards (such as windows). Is there shorter version for this? Is there a way (for example with argparser) to directly expand wildcards during argument parsing?

Thanks

You could avoid the double loop with a chaining iterator, but it hardly seems like an improvement.

for fname in itertools.chain(*map(glob.iglob, sys.argv[1:])):
    print fname

But you could wrap it into a routine:

def allglob(args):
    return itertools.chain.from_iterable(map(glob.iglob, args))
