Dynamically build and return a Python list in a C Python extension

I'm writing a Python extension in C, and I'm trying to figure out how to dynamically build and return a Python list using my extension. I know how to build a list of predetermined size using Py_BuildValue. Is there a way to create a list with Py_BuildValue then append items to that list? Is there a different, and better, alternative?

Solution

  • How about using PyList_Append, just like (modulo reference management and whatnot) you'd use .append in Python?

    Looking at the list API docs may help as well.
