That confidence usually evaporates once you write the first unit test ;)

Do it properly, allow specifying the files on the commandline:
import argparse
def process_files(files, destfile):
# put your real code here
print "merge " + "\n ".join(files)
print "into " + destfile
if __name__ == "__main__":
parser = argparse.ArgumentParser()
parser.add_argument("files", metavar="file", nargs="+")
parser.add_argument("destfile")
args = parser.parse_args()
process_files(args.files, args.destfile)
If you have standard locations for sources and destination you can wrap your
python script into a little batch file containing something like
python \source\path\*.xls \dest\path\merged.xls
and invoke that to get both flexibility and convenience.
