No need to worry about closing a file that was opened read-only. Also, true command-line tools read their args from the command line, not from additional user input. :) The One True Way to write this is as a filter that reads from stdin and writes to stdout. Viz: #!/usr/bin/python3 import sys sys.stdout.write \ ( "".join(reversed(list(sys.stdin))) ) Voilà. :)
