The Pythonic way is to not to preinitialize the list at all. Don't

this is my code:

However, I think it really boils down to a python question: "How do I pass
an integer by reference to a C function?"

It did! Thanks! For one thing now I see that I was barking up
the wrong tree in focusing on a canonical order, when, as the code
you posted shows, it is actually not required for hashing.
In fact, I'd come to the conclusion that frozensets had a c

Thanks! I see that the parenthesis can be dropped, too:

I see. Thanks for this clarification. I learned a lot from it.
I guess that frozenset must have some way of canonicalizing the
order of its elements that is dependent on their Python values but

My first try to write it in Python was something like this:
v = []
for i in range(20):
v[i] = 0
Unfortunately, this doesn't work, as I get an index out of bounds when
trying to
index the v list.
Python can't grow

dicts are unsorted. That means their item-order is undefined. So are sets.
If you want a hash that is independent from the order of items, you
could ensure the it
