I don't see any way in the docs to get the status of an http request, in
particular I want to know whether it's a 404. It does show up in the
guts of the library so maybe I can extract it somehow, but there should
be a simple documented way.
Also, the urllib doc

I like the idea of having some integer math functions like this in the
stdlib; whether in the math module or elsewhere doesn't matter much. In
particular I remember having to implement xgcd on several separate
occasions for unrelated applications, each time
paul rubin added the comment:
I would prefer that %d signal an error 100% of the time if you give it a
float. It should not accept 42.0. It is for printing integers.

Rather than factorial how about a product function, so factorial(n) =
product(xrange(1,n+1)). I do like the idea of an imath module whether
or not it has factorial, and the topic of this rfe has drifted somewhat
towards the desirability

For object serialization and some other purposes, Java encodes unicode
strings with a modified version of utf-8:

Some java applications use it externally. The purpose seems to be to
prevent NUL bytes from appearing inside encoded strings which can
confuse C libraries that expect NUL's to terminate strings. My
immediate application is parsing lucene indexes

Also, according to wikipedia, tcl also uses that encoding.

It would be nice if the library reference manual had type signatures for all
the stdlib functions at some point. It might be possible to extract a lot of
them automatically from typeshed and semi-automatically paste them into the doc
files. It might also
paul rubin added the comment:
Yes, the suggestion was just for the docs, and since those are intended for
human rather than machine consumption, it's fine if there are some blurry cases
where there is no signature. Ideally in those cases, the issue should be
explained in the doc text.

abs takes any value that understands the __abs__ method and returns something
of the same type. In fact there is already a type protocol for it:
https://mypy.readthedocs.io/en/stable/protocols.html#supportsabs-t
So abs's signature would be (x : Abs[T]) ->
paul rubin added the comment:
At first glance, having a typeclass for each protocol (at least the widely used
ones) seems fine. It's inherent in Haskell and a lot of libraries are
organized around a common set of typeclasses--look up "Typeclassopedia" for
descriptions of them.
paul rubin added the comment:
I don't think we're going to accomplish anything continuing the eternal
static-vs-dynamic debate, which in Python's case has already been resolved by
adding optional static typing. It's a done deal, and the issue here is just
how to document it. Erlang (via
New submission from paul rubin :
It would be nice to have frozen Counters analogous to frozensets, so they are
usable as dictionary keys. One can of course create frozenset(counter.items())
but that means the set items are tuples rather than the original set elements,
so it's no longer

paul rubin added the comment:
Yes, the idea was for them to be hashable, to be used as dict keys. E.g. if
you use frozensets to model graphs, you'd use frozen multisets for hypergraphs.
My immediate use case involved word puzzles, e.g. treating words as bags of
scrabble tiles with letters

Yeah I think the basic answer to this ticket is "Python doesn't really have
multisets and a proposal to add them should go somewhere else". Fair enough--
consider the request withdrawn from here.

I don't think the interface needs much bikeshedding, as long as the implementer

Implementation is harder if you want to handle numbers of non-trivial size.

paul rubin added the comment:
I'm the one always asking for more stuff in the stdlib, but above some
simplistic approaches this seems out of scope. Doing it usefully above say
