If you have a bunch of keys that are sortable, you can do something  

 >>> dict = { 1: 'alpha', 4: 'gamma', 2: 'beta', 3: 'delta' }
 >>> keylist = dict.keys(); keylist.sort()
 >>> for k in keylist: print k, dict[k]
1 alpha
2 beta
3 delta
4 gamma

See for more details:

(3) Keys and values are listed in an arbitrary order which is non- 
random, varies across Python implementations, and depends on the  
dictionary's history of insertions and deletions. If items(), keys(),  
values(), iteritems(), iterkeys(), and itervalues() are called with no  
intervening modifications to the dictionary, the lists will directly  
correspond. This allows the creation of (value, key) pairs using  
zip(): "pairs = zip(a.values(), a.keys())". The same relationship  
holds for the iterkeys() and itervalues() methods: "pairs =  
zip(a.itervalues(), a.iterkeys())" provides the same value for pairs.  
Another way to create the same list is "pairs = [(v, k) for (k, v) in

The mailing list strips off many file attachments.  You'd do better to  
put your script on a website somewhere, and mail out the URL to it...
