Hello, if creating new CFunction PyObject *function = PyCFunction_New(function_name, NULL); and then this is the only thing which uses it ("dictionary" stays alive...) PyDict_SetItemString(dictionary, "function", function); do I have to Py_DECREF(function) or not? -- http://mail.python.org/

Re: Redirect stdout to a buffer [Errno 9]

I tried to replace official Python dll with the one built with MinGW and it works. The problem is, that port is very old and so far it seems that official support for building Python under MinGW is nowhere near. I really don't want to use MSVC, so if there's any other way around this, please, let

Redirect stdout to a buffer

Hello, I'm trying to write a simple Win32 app, which may run some Python scripts. Since it is a Windows GUI app, I would like to redirect all output (Python print, C printf, fprinf stderr, ...) to a text area inside the app. In other words, I'm trying to log all the output from the app (C, Python)

Distributing Python environment

Hello, I have an app which I would like to extend with Python. I I saw how to embed the interpreter into C. If I bundle my app with the Python lib (say, python26.dll) I can PyRun_SimpleString() some code. My question is, how do I bundle the rest of the libraries (site, os, elementtree, random, ...)

Executing python script stored as a string

Hello, please, how to execute a python script stored as a string? But let me impose several limitations, so simple "exec" wont work: - if I understood it correctly defining a function in the string and exec-ing it created the function in current scope. This is something I really don't want - sim

Hello, just to recap: last time I asked how to do an interprocess communitation, between one Manager process (graphical beckend) and some Worker processes. I decided to go with sockets, thanks for replies, once more. However, I would like to ask another thing: I would like to collect everyting w

Inter-process communication, how?

Hi, let's say I have two scripts: one does some computations and the other one is a graphical front end for launching the first one. And both run in separate processes (front end runs and that it spawns a subprocess with the computation). Now, if the computation has a result I would like to display

I'm reading the docs now and I stumbled upon something: section "15.3 threading -- Higher-level threading interface" mensions a class "local", in which "... Thread-local data are data whose values are thread specific. ..." Does it mean, I can create global variables whose changing is thread- safe?
