Requires this class:

class bf(object):
def __init__(self,value=0):
self._d = value

def __getitem__(self, index):
return (self._d >> index) & 1

def __setitem__(self,index,value):
value = (value&1L)<<index
self._d = (self._d & ~mask) | value

def __getslice__(self, start, end):
mask = 2L**(end - start) -1
return (self._d >> start) & mask

def __setslice__(self, start, end, value):
mask = 2L**(end - start) -1
value = (value & mask) << start
self._d = (self._d & ~mask) | value
return (self._d >> start) & mask

def __int__(self):
return self._d

Function:

def shinygen(pokemonid):
"""Returns Tuple of Shiny TID and SID for given PID"""
shiny=False
n=0
while shiny == False:
tid=bf(random.getrandbits(16))
sid=bf(random.getrandbits(16))
pid=bf(pokemonid)
n +=1
shiny = True
for i in range(0,13):
if int(pid[15-i]) + int(pid[31-i])+ int(tid[15-i])+ int(sid[15-i])== 3:
shiny = False
break
elif int(pid[15-i])+ int(pid[31-i])+ int(tid[15-i])+ int(sid[15-i])== 1:
shiny = False
break
if shiny:
return (tid,sid)
else:
return False

Demo Program that generates shiny TID/SIDs:
(on dropbox because py2exe is too big to upload [barely])

so basically.. you're generating random tids/sids and finding a match. That's sort of .. silly, as there are more efficient ways to do it.

disregarding the number of errors thrown when running your 'snippet' (you should add you need to do things like setting 'pokemonid' as an input value, defining random), the program downloaded from your dropbox doesn't work.
to clarify, it doesn't give you a shiny tid/sid. only one close to it.
bond and i tested it.

nevermind; it's oddly not working with pokegen for me (but bond's managed to get it work, so i suppose it's fine).

take the upper half of the PID, make that the SID
take the lower half of the PID, make that the TID

bam shiny

I don't know of any better way of generating Shiny TIDs & SIDs considering how shiny calculations are described here: http://www.smogon.com/ingame/rng/pid_iv_creation#how_shiny
anyways the computor will go through over 3000 combinations in less than a second... it doesn't take long... and the program does work i checked it with pokegen...

take the lower half of the PID, make that the TID
ok what if your pid is 11229867

1010101101011|010
1010101101011|010
1010101101011|010
nope not shiny...

or even
9132715
that will not work either...
there are many times that algorithm will fail

the answer to the random problem is simply:

import random
the answer to the other problem is to convert to an integer before you call the function

the answer to the random problem is simply:

import random

exactly .. so shouldn't you, you know, add that in at the top? it's sort of important for the thing to run : p

it's referring to the hexidecimal PID, not the decimal.

each half of the PID is 4 hex characters long, same deal with the TID/SID.

yes i am aware of that but the way to determine shiny is through binary not hex... you can't just set the TID to the upper half and then have the SID set to the lower half... it will work more often than normal but it still fails if you have a PID like 9132715 which if you split it in half has on bits that overlap 3 times

BEEFCAFE

BEEF^CAFE
BEEF^CAFE

BEEF^CAFE^BEEF^CAFE = BEEF^BEEF^CAFE^CAFE = 0
ie always shiny if you do it that way :P

Thats because it was checking all values between position 0 and position 11 not between 0 and position 12
