If you have a bunch of keys that are sortable, you can do something
like:
>>> 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 http://docs.python.org/lib/typesmapping.html 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
a.iteritems()]".
3. My knowledge of networking is at a basic level.
I have attached the script -- it is only 4KB.
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...
