Are you perhaps looking for sys.argv? The following example takes filenames
from the command line and defaults to stdin/stdout:
import sys
def analyse(instream, outstream):
pass # your code
instream = sys.stdin
outstream = sys.stdout
if len(sys.argv) > 1:
instream = open(sys.argv[1])
if len(sys.argv) > 2:
outstream = open(sys.argv[2], "w")
analyse(instream, outstream)
instream.close()
outstream.close()
