I'm trying to make a very simple extension which will return a new copy of a C++ string object to python, and I'm segfaulting in the process. I'm using Python 2.2.2, SWIG 1.3.17 and g++ 3.3. Am I getting something very basic wrong? See code below. -David /* file: dups.cxx */ #include "dups.h"

How I can handle events on a button in a panel inside of a wxHtmlwindow?

Hi all, I would like deleting specific characters from a string. As an example, I would like to delete all of the '@' '&' in the string 'You are ben@orange?enter&your&code' so that it becomes 'benorange?enteryourcode'. So far I have been doing it like: str = 'You are ben@orange?enter&your&code' str = ''.join()

Is there a way to set the EOL character that Python recognizes? For example, I'd like to set it to cr/lf (okay, that's eol characters) when reading a file (DOS text) and set it to just cr when writing out (Mac). Is there a way to do this? Thanks! Jen

Hi list, I am quite new to Python and try to learn Python with a small pygtk program. I am facing a problem which I am unable to solve for myself. I think I have read the documentation and some samples, but however I cannot find my mistake, so hopefully someone can help me with a short hint. This is a small sample application which...

So there I was just sitting there, minding my own business, and in walks one of the programmers, holding "Python in a Nutshell". "Peter," he says, "this has gotta be the best book you've bought so far. Every thing I need to look up, it's got it." THE END (I told you it was a very short story.)

I am researching issues related to emdedding Python in C++ for a project. My project will be running on an SMP box and requires scalability. However, my test shows that Python threading has very poor performance in terms of scaling. In fact it doesn't scale at all. I wrote a simple test program to complete given number of iterations of...

Hi, I'm writing a web app framework which stores pickles in client cookies. The obvious security risk is that some 5cr1p7 X1ddi35 will inevitably try tampering with the cookie and malforming it in an attempt to get the server-side python code to run arbitrary code, or something similarly undesirable. To protect against this, I've...

please let me know if there is a better place to post this ... I am trying to create a shared dictionary which can be accessed via COM. To that end, I have written the code below (at the end). So far this works from a single computer, but if another computer tries to share the data it is unable to see changes, and throws exceptions when...

Does anyone have a function to convert back and forth between NT style paths and POSIX style? It seems trivial, but I want to make sure I don't overlook some obscure detail. Is it a simple matter of translating / and \ characters? FYI, I need a Python function that does what cygpath does so that I can run a script on either NT or UNIX or...

I don't seem to be getting any bites on the earlier post ... so here is my problem in a nutshell.

Dear all, I've a problem using popen2 when using large files. When I use small input files everything works well but when I feed large inputfile to the pipe nothing happens. Is there a maximum bufsize for using the pipe. The code I use is written down here below. Do I need to specify a waittime between line 4 and 5 ? o,i...

Hi, How do I shutdown a win32 COM server? I am scripting Adobe Illustrator through its COM interface. The problem is that Illustrator has memory leaks. And after a few hours of running, Illustrator will start to behave oddly until eventually it refuses the create new COM objects. The solution is to close Illustrator and then restart it.

Hello everyone, I have a problem with python sockets. I broadcast a lot of pickled objects with socket. sendto(...), that works. Ireceive them on the other site with socket.recvfrom(16384) The pickled objects are smaller (like 10000 bytes) than the max bytes. The problem appears if I send too many pickled objects very quickly one after...

Below is some information I collected from a *small* project in which I wrote a Python version of a Java application. I share this info only as a data point (rather than trying to say this data "proves" something) to consider the next time the "Python makes developers more productive" thread starts up again. Background ========== An...

Enter the 4 or 5 parameters needed then end the executable and redirect to another web page which will display some results given from an output file from the...

I find myself often doing the following sort of thing (sorry for lack of whitespace, I don't want the line to break): for entry, index in map(lambda e,i:(e,i),aList,range(len(aList)): # ... This definitely seems like a roundabout way to loop through parallel lists together. Is this map routine truly the easiest/ best/most...

Hi, Below is a description of what I would like to do. Would someone tell me if it is possible and if so, how? I have an array (presumably 'large') that is mallocced in a C function and its values are initialized in that same function. I would like to pass just the pointer to the beginning of the array
