Hi , i'm having some difficulties regarding using the Python/c api.
I'm trying to bulid a deeply nested datastructure (i.e dict within a dict or list within a dict)
Building the data stracture seems ok on interperter, but after few calls to the method
returning the structure, and aft applying the Ctrl+D to exit interperter
i receive a 'segmentation fault'. ?#
Further more when calling the program from python i receive the dictionary as a string!
"{foo: {1:'blah, 2:'boo'}, bar:1}" (i have a feeling these problems are related).
I'm using python 2.3 on a RH9 Linux machine.
Advise would be very much appriciated.
Here is a shorter example of the consept i'm trying to do :
static *PyObject blah (something)
{
PyObject *dict1;
PyObject *dict2;
long x;
dict1 = PyDict_New();
dict2 = PyDict_New();
x = 1;
PyDict_SetItem( dict1, PyString_FromSt ring("foo"),PyI nt_FromLong(x)) ; //setting first dict
//setting dict1 in dict2 and returning dict2
PyDict_SetItem( dict2, PyString_FromSt ring("blah"),di ct1);
// expected {blah:{foo:1}}

You should try Pyrex: http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/
It would make this just as easy as it is in Python.

I'm messing with some code here... Lets say I have this array:

I want to manipulate a deeply nested list in a generic way at a

The value of x is the only one to be changed. With each value of x a
new instance of L is needed so that we actually have a function:

I am writing some C++ wrappers around some legacy C ones - more
specifically, I am providing ctors, dtors and assignment operators for

I have a ton of existing C code that uses these structs. A typical usage

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
