Installing a binary package on virtualenv on windows
Hi I have been using virtualenv on my windows desktop for quite a while now and would really recommend everyone to use it. Something I come across is how can I install a binary dependency in my virtual environment . I need to install lxml and gevent. Both packages are delivered as windows installer (and not always the latest version !!!) and it seems that pip install will not make the job( as it will go through the build process...) Thanks for your help. M -- http://mail.python.org/mailman/listinfo/python-list
ResponseNotReady in httplib
Hi I try to access a web site and it returns me this exception "ResponseNotReady" . I don't know what is the root of the problem and how to sort it out. I am using the excellent python requests library to access the web site but it relies on httplib utlimately. Could someone one explains me the problem and how to sort it out .

I didnt install any external libraries for sax. I think python comes with a standard sax library. And before I had python installed Blender said at startup: "Compiled with Python version 2.5. Checking for installed Python... No installed Python found. Some scripts will not run. Continuing happily" After installing Python 2.5.2 it now says: "Compiled with Python version 2.5.

trying to use sax for a very basic first xml parser
Hi,
I need to parse xml files for the Blender Game Engine. ATM I am trying
to get this script running in the BGE. This is my first script and I
dont have much experience programming...
import xml.sax
class PnmlHandler(xml.sax.ContentHandler):
def __init__(self):
self.inPlace=0
def startElement(self, name, attrs):
if name != "place": return
if attrs.getLength()==0: return
print 'Starting element:', name
print "attrs:", attrs.keys()
id = attrs.get("id", None)
print "id:", id
if name == "place":
self.inPlace=1
def endElement(self, name):
if name == "place":
self.inPlace=0
parser = xml.sax.make_parser()
parser.setContentHandler(PnmlHandler())
parser.parse(open("bpm.pnml","r"))
this works in the IDLE ide. Output:
Starting element: place
attrs: [u'id']
id: p9723441
Starting element: place
attrs: [u'id']
id: p26811937
Starting element: place
attrs: [u'id']
id: p24278422[/code]
but when I copy the script into blender and run it I get:
[code]Compiled with Python version 2.5.
Checking for installed Python... got it!
Traceback (most recent call last):
File "Text", line 27, in
File "H:\Python25\lib\xml\sax\__init__.py", line 93, in make_parser
raise SAXReaderNotAvailable("No parsers found", None)
xml.sax._exceptions.SAXReaderNotAvailable: No parsers found[/code]
Its probably a stupid question but thanks anyway!

Announcement: Python module for pacparser (parses proxy auto-config files)
Fellas, I am mighty pleased to announce the release of python module for pacparser. pacparser is a library to parse proxy auto-config (PAC) files. Proxy auto-config files are already a vastly used web proxy configuration method these days (either directly or via web proxy autodiscovery protocol) and almost all popular web browsers support them. pacparser python module brings in PAC file parsing capability to python programs. Using it, python web software can now work with proxy auto-config files. I am hoping, web software programmers will appreciate it. At least I've been looking for such a thing for a while :). For documentation and available packages, please visit project homepage at http://code.google.com/p/pacparser Direct download links: Source archive: http://pacparser.googlecode.com/files/pacparser-1.0.3.tar.gz Compiled module for python 2.5 and win32: http://pacparser.googlecode.com/files/pacparser-python25-1.0.3-win32.zip I have tested the module to work on Python 2.2 - 2.5 on Linux and Win32.

Announcement: pacparser - a c library to parse proxy auto-config (pac) files
Hi Folks, I am very pleased to announce the release of "pacparser" - a C library to parse proxy auto-config (PAC) scripts. Needless to say, PAC files are now a widely accepted method for proxy configuration management and almost all popular browsers support them. The idea behind pacparser is to make it easy to add this PAC file parsing capability to other programs. It comes as a shared C library with a clear API. You can use it to make any C or python (using ctypes) program PAC scripts intelligent. For documentation and available packages, please visit project home page at: http://code.google.com/p/pacparser For the ones who like to start with source code, here is the link to direct download for source code: http://pacparser.googlecode.com/files/pacparser-1.0.0.tar.gz.

property question
hi all, If I have a class A with A.x, A.y, A.z. A.y and A.z are property and in order to compute the value of them, A.y depends on A.x while A.z depends on A.y and A.x. If I call A.y, and A.z, the value A.y would be computed twice. Is there a smart way to avoid that as to A.y will be recomputed only if A.x has been changed? Now I can define more variables to keep track of what is changed but when there are more variables and the dependency becomes more involved it could be very complicated. Thanks a lot.

Hi,
I have a COM component server that just exposes the IDispatch interface
but when you use it in a VB app you can access other method. I think the
way to access the other methods( as does it VBA for ex) is to use
Invoke but don't know how to do it in python.
Say for ex i want to convert this very simple example with only
IDispatch interface .
import win32com.client
o = win32com.client.Dispactch('Excel.Application')
