Hi,
Trying the multiprocessing module for the first time, I spent quite a
bit on making this code run:
from multiprocessing import Process
import time
def my_process():
i = 0
while 1:
print i
i += 1
time.sleep(0.5)
p = Process(target=my_process, args=())
(This is actually a repost; outgoing netnews server was down for a while.)

Write a one-ahead iterator class, which I have posted before, that sets

If my sleuthing is correct the problem is with these lines
ilow *= self-itemSize;
ihigh *= self-itemSize;
in GapBuffer_slice being computed before ilow and ihigh are compared to
anything.
This particular bug was because ihigh is the maximum 32 bit integer

Hi,
I have searched this list and found out that Python doesn't have a
mutable string class (it had an inefficient one, but this was removed
in 3.0). Are there any libraries outside the core that offer this?
It depends on how

Since the 'and' and 'or' already return objects (and objects
evaluate to true or false), then 'xor' should behave likewise, IMO.
I expect that would be the case if it were ever added to the
language.
I'm not so sure. Did you ever wonder why the any() and all()

In Math and Python, abc means ab and bc, not (ab)c or a(bc).
!= is a comparison operator like ,
Although Python extends the chaining principle to
!=, this is somewhat questionable, because
a b and b c implies a c, but a != b and
b != c does not imply a != c.

The first generator isn't finished, it yielded 1 and None. Second one
is exhausted after yielding a single value (1). The problem is that,
under Python 2.4 or 2.3 both invocations will generate the same trace
output.
This seems to be a deficiency in the trace

To the best of my recollection, the len() function only applies to
container objects; i. e. tuples, lists, strings, etc. an integer
object is not a container, thus one receives an error when sending an
int as an argument for len().

New submission from Ezio Melotti ezio.melo...@gmail.com:
The documentation about the __future__ features [1] only lists the
features available for that particular version, without specifying when
they were added and their effects.
It would be nice to have a table with |feature|version
