I forgot to mention my patch is 3.3-only, sorry - it depends on changes from
#12555 (http://hg.python.org/cpython/rev/41a1de81ef2b#l18.21 to be precise). To
support 3.2 and 2.7:

I've updated the patch according to suggestions from Gregory P. Smith. Thanks
to a change from #12555 (PEP 3151) now just checking for OSError is enough.

Hi
When I am outputting unicode strings to terminal my script works OK, but
when I redirect it to file I get a crash:

I know how to make it work. The question is why outputting to file makes
it crush when outputting to terminal does not.
I have never seen $program file behaving in a different way than
$program in any other language

Jerzy jer...@genesilico.pl added the comment:
Well, I would suggest using the terminal encoding as default one when
redirecting. In my opinion sys.stdin and sys.stdout should always have
the terminal encoding
Alternatively you could make the function sys.setdefaultencoding()
visible
Jerzy jer...@genesilico.pl added the comment:
OK, I give up.
The problem is that one might test a program on terminal and think that
everything is running OK and then spend a reasonable amount of time
trying to find the problem later
Another approach: couldn't utf8 be set as default encoding

good point!

If you want to switch to a different language, consider switching to

I've stumbled upon the following in Python 3:

write() is appending the length of the

Yes, that works as expected, now, similar to 2.6.
Thank you both, Diez and André!

the return

nothing to do with how the language behaves in normal use.
This makes it much clearer!
You are right, output in a shell script is normal, without the return value.
Thank you, Dave.

Actually, it is not possible to use the 'with' statement in the

If you cannot delete the global variable in a function (del makes the
variable local anyway). So trying to delete a global variable should
raise an exception Cannot delete a global variable

It seems that that the result of one fragment of the code depends on the

You could use BZR or SVN to get a copy of the full Lib/test tree. Given

The one thing you will definitely need is the python-dev-package. It will
contain things such as headers and distutils that are needed to build and
install 3rd-party-packages.

Yes, the maximum recursion depth in Python is an artificial limit. But
that artificial limit is built into Python specifically
rather inacceptable. It is not the machine code which matters, but
human effort [provided you spent sufficient time to be fluent in *good*
recursive programming of complex tasks.]

I suspect that it won't improve.
WHY?
It seems that there was already some discussion about consistency and
somebody produced the example: h = {}.update(l) which didn't work,
but I wasn't subscribed to this nsgr, I couldn't follow this affair.
