Python C API: Modify search path

Question

How can I add a speciific directory to the search path using the C API? And a related question: will the changes be local to the application, or is the search path global?

Answer 1

Use PySys_GetObject("path") to retrieve sys.path, then manipulate it as you would any other sequence or list. Changes will be local to the Python interpreter/VM.

Answer 2

You can update search path using the well-known Python code but called from within your C module:

PyRun_SimpleString(
   "import sys\n"
   "sys.path.append('/your/custom/path/here')\n"
);
