Re: Gateway to python-list is generating bounce messages.
Grant Edwards [EMAIL PROTECTED] writes: Could whoever is responsible for the gateway that is grabbing my postings off of Usenet and e-mailing them out please fix the headers in the mail messages so that I don't get the bounce messages? While you're at it, might as well fix it for everybody else too. ;) Its a bit rude to send out mass e-mail messages with headers faked up so that the bounce messages go to somebody else. Messages you submit to the newsgroup are forwarded to the mailing list. When mail messages bounce, the MTA (Message Transfer Agent--the program that handles mail) *should* send the bounce message to whatever is in the Sender header, and only if that header does not exist, should it use the From header. Messages forwarded by the gateway get a Sender header which points back to the gateway. In other words, if a message gets bounced back to the From address, the MTA does it incorrectly. There is nothing the list administrator can do about it. You can try complaining to the postmaster of the bouncing system, but that's about it. In other words, your question in the first paragraph is already implemented and was implemented from the beginning. It is not the gateway's fault that there are systems that don't follow the standards. -- Sjoerd Mullender, python-list administrator -- http://mail.python.org/mailman/listinfo/python-list

What I really want in just the 79, as a3 is not a decimal number, but
when I add the \b word boundaries I get:
In [162]: re.findall('\b\d+\b','this is test a3 attempt 79')

What am I missing?
~Ethan~
Try this:
re.findall(r'\b\d+\b','this is test a3 attempt 79')
['79']
The \b is a backspace, by using raw strings you get an actual backslash
and b.

Re: zip codes
Martin P. Hellwig wrote: Shailen wrote: Is there any Python module that helps with US and foreign zip-code lookups? I'm thinking of something that provides basic mappings of zip to cities, city to zips, etc. Since this kind of information is so often used for basic user-registration, I'm assuming functionality of this sort must be available for Python. Any suggestions will be much appreciated. There might be an associated can of worms here, for example in the Netherlands zip codes are actually copyrighted and require a license if you want to do something with them, on the other hand you get a nice SQL formatted db to use it. I don't know how this works in other countries but I imagine that it is likely to be generally the same. Also in The Netherlands, ZIP codes are much more fine-grained than in some other countries: ZIP code plus house number together are sufficient to uniquely identify an address. I.e. you don't need the street name. E.g., my work address has ZIP code 1098 XG and house number 123, so together they indicate that I work at Science Park 123, Amsterdam. In other words, a simple city - ZIP mapping is not sufficient. -- Sjoerd Mullender signature.asc Description: OpenPGP digital signature -- http://mail.python.org/mailman/listinfo/python-list
[issue4591] uid/gid problem in os.chown
New submission from Sjoerd Mullender [EMAIL PROTECTED]:
On Fedora 8 and 10 using Python 2.5.1 and 2.5.2 (64 bit):
$ grep nfsnobody /etc/passwd
nfsnobody:x:4294967294:4294967294:Anonymous NFS
User:/var/lib/nfs:/sbin/nologin
So the UID of nfsnobody is 4294967294 (-2 if viewed as signed 32-bit int).
import pwd, os
print pwd.getpwnam('nfsnobody').pw_uid
4294967294
os.chown('some file', pwd.getpwnam('nfsnobody').pw_uid,
pwd.getpwnam('nfsnobody').pw_gid)
Traceback (most recent call last):
File stdin, line 1, in module
OverflowError: signed integer is greater than maximum
The reason for this error is that os.chown uses the i format to
convert the second and third arguments. But the valued do not fit in a
32-bit signed integer. uid_t and gid_t are defined as unsigned
quantities on this system.
The bug does not occur on 32 bit Fedora since there the uid and gid of
nfsnobody are 65534.

New submission from Sjoerd Mullender sjo...@acm.org: When a module or feature is deprecated, all uses of the deprecated module/feature should be removed from the non-deprecated part of the distribution (and, I would argue, also from the other deprecated modules).

[issue3216] errors in msilib documentation
New submission from Sjoerd Mullender [EMAIL PROTECTED]: There are several errors in the msilib documentation. I'm sure I haven't found them all, but here are some: - add_data is documented to have two arguments. In reality it has three. - Execute on a View object is documented to have an optional argument. In reality it has a single required argument whose value may be None. - When I click on any of the references to Microsoft documentation, I get a page in Japanese. This is possibly more due to Microsoft than anything else (the links do contain en-us so it is a tad surprising). - There is extremely little information on how to actually use the module. -- assignee: georg.brandl components: Documentation messages: 68831 nosy: georg.brandl, sjoerd severity: normal status: open title: errors in msilib documentation versions: Python 2.5 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3216 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
