[SOLVED] Input parameter: Single file or glob?

[Winfried]

Hello,

As input parameter, I need to allow users to give either a single file (input.txt) or glob (*.txt).

The following code only supports glob:

import sys
import os
from glob import glob

#============= Read file(s) from command line; Windows and *nix shells don't behave the same way
def argGlob(args=None):
	if args is None: args = sys.argv
	
	return [subglob for arg in args for subglob in glob(arg)]

arguments = len(sys.argv) - 1
if arguments < 1:
	print ("Must pass at least one TXT file, or *.txt")
	sys.exit()

for item in argGlob(sys.argv[1:]):

What would be the right way to handle both cases?

Thank you.

Edit: My mistake. I was using a wrong filename as input. The code above works to handle either a single file or a glob.
