You are giving details, but they aren't significant. You can save 256 lists 
with 32 numbers just like you would save 257 or 2560 with 23 numbers. How 
you should save them is largely dependent on how you are using them later. 
Simple methods are pickle.dump() or json.dump().

But what is the problem you are trying to solve by comparing these lists? 
Are you just looking online for lists matching the local ones? Do you want 
to find missing/extra lists? Or are you even looking for changes within the 

How are the online lists provided? Are they text files, is there an API, or 
do you have to screenscrape them from web pages?

Please provide a little more context.
