Unstash in Python

I once wrote a Java version of the infamous unstash script, written in Perl.

As I am picking up Python (so refreshing, so little clutter) I thought it would be nice as a little practice to rewrite it in Python as well. And it is really compact.

This is what I came up with:

#!/usr/bin/python
# (c) 2013 Jeroen Zomer   http://strelitzia.net
import sys
def parseStash():
    if len(sys.argv) < 2:
        print "please add the stashfile as argument"
        return
    print "extracting password from: " + sys.argv[1]
    for b in open(sys.argv[1]).read():
        if ord(b) == 0xf5 :
            return 
        sys.stdout.write( chr(ord(b) ^ 0xf5) )
parseStash()

or if we would take the absolute bare minimum, it gets really impressive how powerful and compact python can be:

import sys

def parseStash():
    for b in open(sys.argv[1]).read():
        if ord(b) == 0xf5 :
            return
        sys.stdout.write( chr(ord(b) ^ 0xf5) )

parseStash()

This reminds me of the famous oneliners we used to have in Basic or the JavaScript 1k competitions…
