Hex | str2hex and hex2str

Question

the other day one of my clan-members started talking in leetspeak ..
and called me a noob so, i decided to show him;
told him real men speak in hex; not leet/hex -speak
but of course i can't remember the ascii codes .. so i wrote these two scripts to do the conversion..

import sys, signal
from string import replace
_head = "hex2str.py | converts a hex2str.py string back to text\npress Ctrl+C to exit.\n"
print _head , ' - '*(len(_head)/4)
#signal handle is just cosmetik? to prevent the ugly error
#if you kill the script with ctrl+c
def signal_handler(signal, frame):
print "\n"
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
def hex2str(st):
out = ''
while len(st) > 0:
out += chr(int(st[0:2], 16))
st = st[2:]
return out
while True:
_in = raw_input('hex2str:> ')
if len(_in) > 0:
print ' ',hex2str(_in).replace('x',' ').upper()

If by "correct output", you mean you want something like 4bytes (0xBADDF00D) converted to 8bytes ("BADDF00D" in normal display), then there are several ways ...
