Thanks. read() did not work when I opened the file with:
f = open(someFilePath)
But after changing to f = open(someFilePath, "rb") the read() works
fine.

f = open(someFilePath, "rb")
content = []
for data in content.read()
content.append(data)
fullContent = "".join(content)
Is there a more efficient way of doing this? I'll be running this
operation on 10,000+ files where each file is an image file with size
50k-100k

I was hoping that when the compiler finds decorators with wrapers that
have the same signature it can some how "magically" combine them into
one function (which gets called at run time) and

The actual code for the page layout is in a preppy template. But the
calls to the template engine are made in the

I was fearing that. The expose decorator is the only one that comes
with cherrypy. The other ones are mine and are of the format:

I'm building an application with cherrypy and have started using
decorators quite extensively. A lot of my exposed functions look like:
@expose
@startTransactrionAndBuildPage
@partOfTabUi(tabId)
@convert(arg1=int, arg2=str)
def do_main_page(self, arg1, arg2):

I read some of the earlier threads which essentially said that numpy is
about 3-4 times slower then Numeric for smaller arrays. I'm assuming
that applies only to operations that apply to the whole arrays.
I was curious how the performance of the following operations would
compare though:
1. Copyin
I use Numeric extensivly and have been thinking of migrating to Numpy.
I have a couple of questions:
1. Will the speed of creating new arrays, copying new arrays and
slicing new arrays be similar to Numeric?
2. I have some pyrex code that uses Numeric header files. will they be
compatible with nu
I use python to script my application. Users will be able to write
their own python scripts which are then run a grid of servers. I want
to be able to capture syntax errors in submitted users scripts and then
display them (with line numbers) back to the user.
I also want to check for obvious thing
Here's a recent post of wingide:

I would strongly recomend it. Works great.

I have the debug and the python shell just below the editor and the

swtich tabs when you search or go to the python shell this way. The
source assistant tab is always visible. Since I did not configure it in
any special way, I as
I haven't used an IDE in a long time but gave wing ide a try because
I wanted the same development platform on Linux and Windows.
I'm currently using Ultraedit and it works fine but needed something
more portable as I'm moving my main platform over to Ubuntu. I first
tried jedit and was reasonably
Unfortunately this in not an options since all the processes share
objects in memory which are about 1gig for each node. Having a copy of
this in each user process is just not an options. I think I'm going to
use RestrictedPython from zope3 svn which should take care of 70-80 %
of the problem.

I would strongly recomend ubuntu server 5.1. I installed it on about 15
servers. Its secure out of the box. no ports are open. It comes with
python 2.4.1 and a ton of python modules. The install requires only 1
cd and uses only 400 mb.

This can not be done at compile time but can be cought at execution
time on linux by the following recipe:

No. I was hoping to leverage the work done for restricted pythonscript
by zope at:
http://www.zope.org/Control_Panel/Products/PythonScripts/Help/PythonScript.py
which is similar to what I want to do as well.

I have so many things to do to get this to production and writing a
mini language would be a full project in itself. :-<.
Is there an easy way to do this? If not, I'll go with the steps
outlined in my other post.

I'm going to have write some custom performance monitoring functions to
get notified when some models are running for ever and be able to
terminate them.
