Guido's time machine strikes again. Python 3:
py> s = {1, 2, 3}
py> type(s)
with {,} as an empty set
That looks like a typo. I don't think that having a literal for empty sets is important enough that we need worry about the lack.
An ordered dict could be defined as [ item1: value1, item2: value2 ... ] with [:] ase an empty odered dict
I think that's been proposed before. I don't hate that suggestion, but I don't think its very useful either. We already have a de facto "Ordered Mapping" literal that can be passed to the OrderedDict constructor: OrderedDict( [(key1, value1), (key2, value2), (key3, value3), ...] ) Its not quite as compact, but it isn't too awful. And if you really don't like it, try: OrderedDict(zip(keys, values)) -- Steven
