Now that rexec is gone, is there any code or information available on executing Python in a restricted environment? And before I roll my own solution, exactly where the security holes in rexec anyway? (I know one way of getting a restricted environment: butcher the Python interpreter by removing everything that's even remotely dangerous,...

QOTW: "the DOM API is designed for consultants, not for humans or computers" -- Fredrik Lundh giving solace to a confused DOM API user QOTW: "Python enjoys making tradeoffs that drive *someone* crazy <wink>" -- Michael Hudson's signature line attributed to Tim Peters Discussion ---------- Alex Martelli shows the classic example for...

I've just installed Python 2.3.1 on a SGI system running Irix 6.5, using the SGI versions of cc and CC, as the local gcc is broken. There were a lot of error messages, which seems to be normal. I'd like to hear comments about how usable the resulting Python is likely to be, and how to fix some of the install errors. So far I don't know...

Hi folks- I'm about to move from a Solaris 8/SPARC environment to a Dell running RedHat 9. Are there any issues I need to be aware of in bringing my Python code over (mostly scientific computation)? In particular, I know earlier versions of RH shipped with an "old" Python installed as "python" and that installation of more recent versions...

I am trying to print some special characters, but they come out as different characters in the Python console. If I have a script like this: # -*- coding: latin_1 -*- print "Mädchen" print "M\xE4dchen" Both statements produce a capital sigma where they ä should be. Typing "\xE4" directly in the console also spits back a sigma.

I really have two related questions. 1) Is it possible (without recompiling and changing the core Python behavior) to write functions that utilize the same syntax as built-in functions? IE, can I create a function that does this: >>>printCaps "hello" #note no parentheses HELLO

One of my recent projects has involved taking an accretion of sh and perl scripts and "doing them right" - making them modular, improving the error reporting, making it easier to add even more features to them. "Of course," I'm redoing them in python - much of the cut&paste reuse has become common functions, which then get made more robust...

The parser library module only records source line numbers for tokens. I need a parser that records ranges of line and character locations for each AST node, so I can map back to the source. Does anyone know of such a thing? Thanks Jonathan

I want to write an NT service that will intercept any outgoing smtp traffic, like Norton Antivirus does. Can anyone tell me how I can do something like this in Python? I do not know how to intercept the outgoing traffic, specifically. Any help is greatly appreciated. Thanks, Scott

Hello, I was using os.popen function to get CVS command output to string from script.. Same commands worked well with Windows, but Linux seems to have problem with those. Whole CVS commands seem to froze or given commands aren't executed right at all. I had to replace os.popen commands with os.system. os.system commands just

Hi, I'm new to python, so excuse me if i'm asking something dumb. Does python provide a mechanism to implement virtual functions? Can you please give a code snippet also...:) Thanx in advance -Prabu.

Hello, I'm looking for a Python module that will let me stream real-time data, in my case video data. The current C++ code I use, based on UDP, is unsatisfactory and I would like to move to something the the RTP protocol. Python does not come with RTP support, and the only RTP related stuff

I know I've seen this elsewhere but I can't seem to find the answer.... I have Python embedded in a Windows application. I want to debug the non- python part of the app without using the debug versions of python22_d.dll and the myriad of other _d.pyd's. I do have all the _d files (62 at last count!!!) but I didn't put them in my delivery...

Hi, I use the unittest module for testing a given module's functionality, by lumping several test classes and then at the end a simple if __name__ == "__main__": unittest.main() In one of these, I get, at a DOS prompt the following weird result:

I use the newsgroup mainly via my Web browser and Google. Over the last few days, when I click on a link to a thread, I've been frequently getting the message "Unable to find thread." Does anybody know what's going on?

I've installed Eclipse 3.0 and the latest pyeclipse. I can get the editor run - at least I think so, because it seems to do reasonable syntax highlighting. However, I can't get the Python console window to appear (Unable to instantiate view: org.python.pyeclipse.views.ConsoleView), nor can I get python to run to completion. The MSWindows...

Dear all, I want to use python as my GUI to load a 3D volume (vtkImageData), and use a pointer to pass this 3D image to my own C++ class.
