Newbie needs regex help
I'm getting bogged down with backslash escaping.
I have some text files containing characters with the 8th bit set. These
characters are encoded one of two ways: either =hh or \xhh, where h
represents a hex digit, and \x is a literal backslash followed by a
lower-case x.
Catching the first case with a regex is simple. But when I try to write a
regex to catch the second case, I mess up the escaping.
I took at look at http://docs.python.org/howto/regex.html, especially the
section titled The Backslash Plague. I started out trying :
d...@dan:~/personal/usenet$ python
Python 2.7 (r27:82500, Nov 15 2010, 12:10:23)
[GCC 4.3.2] on linux2
Type help, copyright, credits or license for more information.
import re
r = re.compile('x([0-9a-fA-F]{2})')
a = This \xef file \xef has \x20 a bunch \xa0 of \xb0 crap \xc0
characters \xefn \xeft.
m = r.search(a)
m
No match.
I then followed the advice of the above-mentioned document, and expressed
the regex as a raw string:
r = re.compile(r'\\x([0-9a-fA-F]{2})')
r.search(a)
Still no match.
I'm obviously missing something. I spent a fair bit of time playing with
this over the weekend, and I got nowhere. Now it's time to ask for help.
What am I doing wrong here?

The backslash trickery applies to string literals also, not only
regexps.
Your string does not have the value you think it has. Double each
backslash (or make your string raw) and you'll get what you expect.

D'oh! I hadn't thought of that. If I read my data file in from disk, use
the raw string version of the regex, and do the search that way I do
indeed get the results I'm looking for.

cursor.lastrowid is always in reference to the last query executed by

previous value of cursor.lastrowid no longer exists. If you need it

This can be done like so: import urllib2 try: asock = urllib2.urlopen(http://www.foo.com/qwerty.html;) except urllib2.HTTPError, e: print e.code The value in urllib2.HTTPError.code comes from the first line of the web server's HTTP response, just before the headers begin, e.g. HTTP/1.1 200 OK, or HTTP/1.1 404 Not Found. One thing you need to be aware of is that some web sites don't behave as you would expect them to; e.g. responding with a redirection rather than a 404 error when you when you request a page that doesn't exist.

Re: doubt on csv file
here is what am trying to do, first am trying to open it in a read
mode, and checking each row by row , if it is not found till my last
row, i want to append it to the last row , so how should i do that.
file = open ('C:\some.csv','r')
reader = csv.reader(file)
for row in reader:
print row
How can i update at the last row.
This newbie's idea is that you'd want to keep track of whether you'd found
the item you are looking for. If not found, close the file, reopen it
in append mode, and write the new row. For example:
f = open ('C:\some.csv','r')
rdr = csv.reader(file)
found = 0
for row in rdr:
if row[0] == 'YYY': found = 1
print row
if found:
print No need to do anything more
else:
f.close()
f = open(c:\\some.csv, 'a')
f.write(The new row data)
f.close()
I am admittedly a newbie; I'm sure more experienced users will have more
efficient suggestions. Note that I did change file to f to avoid hiding
the file method and changed reader to rdr for the same reason.

Re: Newbie: executing a system command from my Python app
Few points points: 1. Generally: I would try to minimize system calls. They make your code less portable. Excellent point. In this case the app will never live anywhere other than one specific FreeBSD machine, but I do appreciate the value of the advice anyway. Therefore... 2. Look into the shutil module for recursive deletion. 3. Use os.path to construct paths. Try to avoid, for example, c:\blah\blah on dos, '/blah/blah' on unix, etc. Have done so. Thanks for pointing out the shutils module! I keep finding more and more excellent modules available. Do we have a Python equivalent to Perl's CPAN? 4. If you only have one argument, you don't need a tuple for string formatting. 5. (dateYest) is not a tuple anyway--the parentheses are superfluous 6. Single item tuples can be created with (anitem,) (notice the comma). That helps. I had somehow gotten the mistaken idea that string formatting always needed a tuple, and overlooked the trailing comma. I've applied that correction to several of my other Python scripts as well. -- http://mail.python.org/mailman/listinfo/python-list
Newbie: executing a system command from my Python app
I'm writing a Python replacement for a particularly ugly shell script. we
are running mimedefang on our mail server, moving spam and virus messages
to a quarantine directory. This little python script successfully chdir's
to the quarantine directory, identifies all of the quarantine
subdirectories for yesterday's messages, and stuffs them into a tar file
in an archive directory. I then want to delete for successfully tarred
files and the subdirs they live in.
By way of further explanation, quarantined messages get broken into files
named ENTIRE_MESSAGE, HEADERS, RECIPIENTS, SENDER, and SENDMAIL-QID, and
get stored in subdirectories named qdir--MM-DD-hh.mm.ss-nnn, where
Y-M-D is the date received, hms is time received, and nnn is to allow for
up to 10 messages to quarantined any given second.
I know I can do this by descending into the directories I've identified
and unlink()ing each of the files, but I'd like to take a shortcut like:
retval = os.system('rm -rf /var/spool/MD-Quarantine/qdir-%s*' %
(dateYest)) and indeed code written that executes without any errors.
Unfortunately it also leaves a bunch of qdir-2005-12-11-* files sitting
around when I run it on 12-11.
Have I overlooked some basic operation of the os.system() call? From all
I've seen in the online docs and O'Reilly's Programming Python it looks
like it should be working.
Here's my complete script:
#!/usr/local/bin/python
import glob, os, tarfile, time, datetime
DATE_FMT = %Y-%m-%d
filelist = []
yest = datetime.date.today() + datetime.timedelta(days = -1)
dateYest = yest.strftime(DATE_FMT)
os.chdir(/var/spool/MD-Quarantine)
try:
tar = tarfile.open(/usr/local/archives/MD-Q/%s.tar.gz % (dateYest),
w:gz)
for file in glob.glob(qdir-%s* % (dateYest)):
tar.add(file)
filelist.append(file)
tar.close()
except TarError:
print The quarantine file archiving program threw a TarError
exceptionexit()
cmd = rm -rf /var/spool/MD_Quarantine/qdir-%s* % (dateYest)
print About to execute , cmd
retval = os.system(cmd)

Re: Python web publishing framework like Cocoon?
Is there a Python web publishing framework like Cocoon? I found Maki http://maki.sourceforge.net/ but it was last updated in 2003 and its author says that he doesn't want to make another release...

Re: how to handle two forms in cgi?
My question is: How let these two form works together? I try to use two codes for these two forms, e.g. Login.py for login form and search.py for search form. But when user input data in search form and click its submit button, it just comes back to login form. Second form doesn't work. Any help is appriciated! It sounds like the action attribute in the 2nd form's form tag is not pointing to search.py. -- http://mail.python.org/mailman/listinfo/python-list
Timeout in urllib2
I'm writing a system monitor script that needs to load web pages. I'm using urllib2.urlopen to get the pages, and I'm attempting to set the timeout value using socket.defaulttimeout. Specifically, I'm calling socket.defaultttimeout(10), then calling urllib2.urlopen to fetch a web page that never gets delivered. My code waits about 30 seconds before terminating. I am about to add threading to my app so that delays on a few servers won't be a critical issue, but I'd still like to understand why the call to socket.defaulttimeout doesn't affect the timeout on my urlopen calls. My code follows. #!/usr/local/bin/python import socket, time socket.setdefaulttimeout(10) import urllib2 def doHttpTest(): url = http://url.that.never.returns; t_start = time.time() if httptest(url): print Error on site , url t_end = time.time() t_diff = t_end - t_start def httptest(url): timeout = 10 socket.setdefaulttimeout(timeout) try: req = urllib2.Request(url) urllib2.urlopen(req) except urllib2.HTTPError, e: if e.code == 401: return 1 elif e.code == 404: return 1 elif e.code == 503: return 1 else: return 1 except urllib2.URLError, e: return 1 else: return 0 if __name__ == '__main__': try: doHttpTest() except KeyboardInterrupt: print Exiting... -- http://mail.python.org/mailman/listinfo/python-list
Re: Using Which Version of Linux

So, can anyone tell me which flavour of linux i should use, some say that Debian is more programmer friendly, or shold i use fedora, or Solaris. Because these three are the only ones i know of that are popular and free. Personally I would recommend staying away from Fedora unless you have a friend who is well-versed in it and willing to help. I like the distributin ok (I run it on the laptop I'm writing this from) but it uses RPMs for package distribution, and the rpm tools don't know how to automatically downloaded dependencies like yum or apt do. Because of that I have to say that the RPM package tools suck quite badly. Debian and SUSE are both pretty good choices. -- http://mail.python.org/mailman/listinfo/python-list

Python 2.3.4, Berkeley db 1.85, db file format not recognized
I'm working on a script that will interface with sendmail on my FreeBSD box. I'm trying to read my access.db file (yes, it's for a quick and dirty SMTP-after-POP application). I'm trying: import bsddb bsddb.hashopen(access.db) but I get: bsddb._db.DBInvalidArgError: (22, 'Invalid argument -- access.db: unexpected file type or format') This suggests to me that my bsddb is too new. I really don't want to rebuild sendmail with a more current db, as I'm afraid of breaking sendmail. Any suggestions on how to read this file?

Re: Parsing XML - Newbie help
Hi rh0dium wrote: I am relatively new to python and certainly new to XML parsing. Me too. However there are plenty of good docs/tutorials available to help with both XML and using it in Python. For XML you may wish to look at http://www.w3schools.com/. It has a very accessible set of tutorials on XML and related technologies, which I find make it very quick to get up and running. For what you are trying to do you may wish to look at XPath, or ideally XQuery although I'm not sure there is an XQuery implementation in Python. For Python and XML there is Mark Pilgrim's excellent chapter on Parsing XML with xml.dom.minidom (http://diveintopython.org/xml_processing/index.html). The is also the PyXML project at Sourceforge (http://pyxml.sourceforge.net/). A list of useful links is maintained there (http://pyxml.sourceforge.net/topics/). You may also wish to investigate resources at the Python XML SIG page (http://www.python.org/sigs/xml-sig/). These are just some of the sources of information I am using. Hope this helps.
