sub-shell errors

Hi all,

I'm trying to create a sub shell environment ( i
haven't really got a reason, its more of a test,
although hopefully it will make life easier ;P )
but whenever i try to call the commands  i've created
i get :
[ ice being the sub-shells name ] 

ICE> help
Traceback (most recent call last):
  File "./console.py", line 27, in ?
    for cmd, callback in cmds:
ValueError: too many values to unpack

the code that is supposed to parse out the commands :
( all the commands are in a seperate file called
commands.py, just for ease of maintance and
readability )
---begin----
import commands

userInput = str()

while(1):
	
	userInput == raw_input('ICE> ')
	cmds = { 'help' : commands.displayHelp, 'version' :
commands.displayVersion,
	'authors' : commands.displayAuthors, 'exit' :
commands.exitIce}
		
	for cmd, callback in cmds:
		if userInput == cmd:
			callback()

-----end------

I've tried several methods of going around this error,
but none seem to work, the only other way i could do
it is with a big series of if and elif statments ..
but i don't reall want to for maintanance reasons ..
:P 

if i print cmds ( the array that holds the commands )
:

{'version': <function displayVersion at 0x403db17c>,
'exit': <function exitIce at 0x403dbc6c>, 'help':
<function displayHelp at 0x403d6f44>, 'authors':
<function displayAuthors at 0x403dbc34>}


Thanks 
Bigbowser
