If I iterate over it, the entries will appear in any order, as
opposed to
what I see above. However, in the config file, I'd like to keep them
in the order above.
Thats tricky! Dictionaries are not sorted and do not retain insertion
order.
If you can define a sort order you can use sorted:
d = {1:2, 3:4, 8:9, 5:7}
for n in d: print n
...
8
1
3
5
for n in sorted(d): print n
...
1
3
5
8
But you need to have an order that will work with sorted().
Its not just the order you add items to the dict. To store an
arbitrary order I suspect you would need to maintain a
secondary list with the keys in the order of insertion.
The most reliable way to dop that would be to subclass
dict. Somebody may already have done that so its worth
a google...
