What you probably want here instead is an ordered dict, and not a sorted 
dict. It's easy enough to sort the keys, but maintaining an other than 
sorted order, such as the order the items were added to the dict, or the 
order in which you will need the items from a dict isn't as easy and 
requires keeping a duplicate list of the keys.

Is this what you are looking for?

 >>> import inspect
 >>> import __main__
 >>> inspect.getmembers(__main__, inspect.ismodule)
[('__builtins__', <module '__builtin__' (built-in)>), ('__main__', 
<module '__main__' (built-in)>), ('inspect', <module 'inspect' from 
'C:\Python24\lib\inspect.pyc'>)]


This is how PyDoc does it.  I just happen to be in the middle of 
attempting to rewrite it so it's more modular and easier to extend.  ;-)
