I have a library change request: currently partial Objects created by
functools.partial has the "keywords" attribute. However, the standard
name for something like it is kwargs. I request that it be renamed to
"kwargs".

I have always thought that re's sub and subn are misnamed. I always
mis-remember them as 'replace'. Can they either be renamed to
"replace" and "replacen" or at least the new functions added?

>From PEP 3116: "BufferedRandom implementation is for all random-access
objects, whether they are read-only, write-only, or *read-write*."
(emphasis mine) However, from the pseudo-code for open(),
"if reading + writing + appending > 1:
raise ValueError("can't have read/write/append mode at once
A quick question:
What does the "+" mode do? I couldn't find much on google (except that it is
called "updating").

+1 from me too if you only need to define __lt__ and __eq__ and __le__ and
__gt__, etc, will default to that. If it dosn't default to those, I feel
that one would need to write too many functions.

Ok, I do see your point, but how would one pass in a custom comparison
function to sorted?

The default factory that collections.defaultdict takes cannot use key. Is
there a way to have the default factory take the key into consideration? For
example
d = collections.defaultdict(lambda title: BookShelf(title))
If not, I propose that it be added.

I request the addition of prod():
def prod(seq):
s = 1
for x in seq:
s *= x
prod is always as useful as sum()

Currently,
True or False
works as expected, but
True xor False
is invalid. I don't see a reason why and, or, not are valid python keywords
but xor is not. Can this be added in python 3.0 for completeness?
Also,
True & False, True | False, True ^ Fals, True != False
works but
!True, !False
dosn't.
I have a few questions.
1) Where can I suggest API changes?
2) Are there any plans to add more modules in python 3000 either in python
3.0 or later?

I don't think there is any chance that this will change in python 3000
but...
Why is the builtin types lowercase when the convention is for classes to be
in CamelCase? For example, frozenset versus UserDict. Was there any reason
that this is the way it is or is it just a "wart"?

I think that WeakKeyDictionary and should be renamed to WeakKeyDict (same
with WeakValueDictionary). This will make it consistent with dict and
collections.defaultdict.
