I know about os.nice() it works perfect for parent process, but I need to do renice of my child subprocesses. I found way to do this, but it seems to be not very handy and too excessive:
os.system("renice -n %d %d" % ( new_nice, suprocess.pid ) )
And it isn't return resulting nice level after renicing.
Is there more clean way to renice subprocesses in python?
given a URL like www.mysampleurl.com is it possible to crawl through the site and extract links for all PDFs that might exist?
I've gotten the impression that Python is good for this kind of stuff. but is this feasible to do? how would one go about implementing something like this?
also, assume that the site does not let you visit something like www.mysampleurl.com/files/
As some of you may know in python2.7/3.2 we'll get OrderedDict with PEP372 however one of the reason the PEP existed was because everyone did their own implementation and they were all sightly incompatible.
So which one of the 8 current implementations link text is backwards compatible with the 2.7 odict from python 2.7 in a way we can start using that now and depend on 2.7 in a couple of months?
I have created some program using python on Windows Vista. But I want to deploy it on Windows XP. Is it necessary to make new build on windows XP? Or there is possibility to make build that will work on both of these systems?
EDIT (EDIT 2 - very simple program does not work also):
My setup:
from distutils.core import setup
import py2exe
setup(console=['orderer.py'])
Using dependency explorer i checked that dependencies are:
msvcr90.dll
kernel32.dll
+ntdll.dll
I was wondering if it's frowned upon to use the decorator module that comes with python. Should I be creating decorators using the original means or is it considered okay practice to use the module?
how would i tranfoms this curl command:
curl -v -u 82xxxxxxxxxxxx63e6:api_token -X GET https://www.toggl.com/api/v6/time_entries.json
into urlib2?
I found this tutorial: http://www.voidspace.org.uk/python/articles/authentication.shtml
but they use a password and username. I can only use an API token.
Thank you.
see also this question:
Urllib2 raises 403 error while the same request in curl works fine
my python xml parser fails if there´s a comment at the beginnging of an xml file like::
<?xml version="1.0" encoding="utf-8"?>
<!-- Script version: "1"-->
<!-- Date: "07052010"-->
...
is it illegal to place a comment like this?
According to this python page, oursql looks very cool.
oursql has real parameterization.
oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client.
oursql can both insert rows lazily and fetch rows lazily.
oursql has unicode support on by default.
So, Anyone start using it in the live projects and could share pros and cons over it?
I get an "unrecognized HTTP method" when trying to do a REPORT request using httplib and gae. Is there a workaround available? An httplib patch for gae? Do you I have to find another host in order to do this natively?

How would you write a list comprehension in python to generate a series of n-1 deltas between n items in an ordered list?
Example:
L = [5,9,2,1,7]
RES = [5-9,9-2,2-1,1-7] = [4,7,1,6] # absolute values
I have the following file like this:
2 qid:1 1:0.32 2:0.50 3:0.78 4:0.02 10:0.90
5 qid:2 2:0.22 5:0.34 6:0.87 10:0.56 12:0.32 19:0.24 20:0.55
...
he structure is follwoing like that:
output={}
rel=2
qid=1
features={} # the feature list "1:0.32 2:0.50 3:0.78 4:0.02 10:0.90" output.append([rel,qid,features])
...
How can I write my python code to load the data, thanks
I'm using Pisa/XHTML2PDF to generate PDFs on the fly in Django. Unfortunately, I need to include SVG images as well, which I don't believe is an easy task.
What's the best way to go about either a) converting the SVGs to PNG / JPG (in Python) or b) including SVGs in the PDF export from Pisa?
This code should automatically connect players when they enter a game.
But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable).
How could I make it thread safe?
def join(userId):
users = memcache.get('room_1')
users.append(userId)
memcache.set('room_1', users)
return users
I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.
I may have string like,
"""Hello, %(name)s,
how are you today,
here is amount needed: %(partner_id.account_id.debit_amount)d
"""
what would be the best solution for such template may i need to combine regular expression and eval, input string may differ like $partner_id.account_id.debit_amount$ - for the moment I've kept as python string format - just for testing.
I'm using Python to read and write SAS datasets, using pyodbc and the SAS ODBC drivers. I can load the data perfectly well, but when I save the data, using something like:
cursor.execute('insert into dataset.test VALUES (?)', u'testing')
... I get a pyodbc.Error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)') error.
The problem seems to be the fact I'm passing a unicode string; what do I need to do to handle this?
I'm using textmate for the first time basically, and I am lost as to what keys map to these funny symbols.
using python bundles, what keys do I press for:
run
run with tests
run project unit tests
Also, with textmate, do I actually define a project in textmate or do I just work on the files and textmate doesn't create its own .project type file ?
I need to run a lot of Django management commands in the crontab and want to log the output of each run to a special timestamped file. Is there a Django or Python module to help me do this or do I just have to roll my own?
Dear All,
Let say I have a model:

How do I query if I wanted to search all empty property (not None, just empty) in C using python?
I'm using python's sendmail in the following way:
msg = <SOME MESSAGE>
s = smtplib.SMTP('localhost')
s.sendmail(me, you, msg.as_string())
s.quit()
This usually works fine but it fails when the message is pretty big (around 200 lines). Any ideas what can cause this?

Hi all,
i am quite new in python.
I am receiving (through pyserial) string with data values.
How can I parse these data to particular data structure?
I know that
0-1 byte : id
2-5 byte : time1 =>but little endian (lsb first)
6-9 byte : time2 =>but little endian (lsb first)
and I looking for a function:
def parse_data(string):
data={}
data['id'] = ??
data['time1'] = ??
data['time2'] = ??
return data
thanks
