You could store arrays associated with string names, or other  
identifiers, (as opposed to integer indices) in a python dict.

Global and local namespaces are also just dicts that you can grab with  
globals() and locals(), if you really want to look up variable names  
algorithmically, but I promise you that this is really not what you  
want to be doing.
