Change the above line to
print sys.argv[1].decode("string_escape")
s.decode("string_escape") returns a new string with all c-style escape
sequences converted into the corresponding characters. This is an abuse -
ahem, example of a general mechanism. Look for codecs if you want to learn
more about it.
