Glad to see you solved it! A couple of minor considerations:
	- I would suggest you use a variable name other than 'dict', as that  
shadows the built-in 'dict' type
	- I would suggest using the idiom 'item_0%ss' % brain rather than  
'item_0' + brain + 's', in case at some point you want to change the type  
of 'brain'
