Jul 15, 2016 at 16:10 comment added arekolek It would be clearer to write line.rsplit(maxsplit=2). Also, I would pass op to caesar_cipher(msg.lower(), int(n), op) and there would have if op=='d': n = -n. You don't need the assignment before write, you could pass the result directly. I also posted a different implementation of caesar_cipher that may be more Pythonic.
Nov 25, 2013 at 23:50 comment added 200_success I would move the open() operations outside process_file(), so that the caller has the flexibility to call process_file(sys.stdin, sys.stdout).
