Pythonians,

I'm interested in using pytables to store some data in which some of the information is stored in the form of a python dictionary.  The problem is as follows.  How exactly do I save both the keys and values from a dictionary that contains values of different python types.  For example if I have the following dictionary:

import numpy as N
test_dict = dict(a = 3.14159, b = 'some string', c = [1,2,3,4,5], d = N.arange(0,10,0.1))

How can I commit this structure to disk using PyTables?  Do I need to break it up into its individual components and then store them as individual pieces using
test_dict.iteritems (this seems unattractive) or is there a better way?  Any help would be appreciated.

Cheers,

Brian
