Hi, I read the Python/C-API and they say I should not use PyArg_Parse() anymore but use PyArg_ParseTuple(). My problem is that I retrieve an PyObject * out of PyDict_GetItem(...) so this is a single object and not a tuple. PyArgs_Parse() is the only API-Function to get a C-"string" out of …

Hi, may anybody tell me why there is a init AND a new-method? Why not using one constructor-method like we have to use in java and other OO-lanuages?? Would be nice if somebody can give me an idea about that. Thanks a lot Jonny

Hi, the Python/C-API says that we allways have to return owned references.

Hi, I read that e.g. PyTupe_SetItem() steals a reference to the given object but I didn't get what that mean to me and why doesn't PyDict_SetItem() do it either? Jonny

Hi, may anybody tell me what "initializes the interpreter" mean in detail? Does this function starts a new process or thread of the python interpreter in the background or what does this call do?? Hopefully somebody can give me a little hint :) Jonny

Hello, I've read the python doc (C-API) and was wondering about the two reasons to extend python with C. The first reason is to implement new build-in object types and the second one is to call C-Library functions and system calls. Ok, I think i got the second one but …
