Thank you for that suggestion. It allowed me to replace six lines of code with
one. :)

Hi and thanks very much for your comments on reference counting. Since I'm new
to the C_API that will help a lot. I know that reference counting is one of
the difficult issues with the C API.
I just posted a reply to Inada Naoki showing how I solved the problem I posted
yesterday.
Thanks
With the help of PyErr_Print() I have it solved. Here is the final code (the
part relevant to sents):
Py_ssize_t listIndex = 0;
pListItem = PyList_GetItem(pFileIds, listIndex);
pListStrE = PyUnicode_AsEncodedString(pListItem, "UTF-8", "strict");
pListStr = PyBytes_AS_STRING(pListStrE

I'll do that and post back tomorrow. The office is closing and I have to leave
now (I'm in Seattle). Thanks again for your help.

It means exception happened.
If you are writing Python/C fu
I'm using Python 3.8 so I tried your second choice:
pSents = PyObject_CallFunctionObjArgs(pSentMod, pListItem);
but pSents is 0x0. pSentMod and pListItem are valid pointers.

Right you are. In that case should I use Py_BuildValue and convert to tuple
(because it won't return a tuple for a one-arg), or should I just convert
pListStr to tuple? Thanks for your help.

Thanks for your reply.
I eliminated the DECREF and now it doesn't segfault but it returns 0x0. Same
when I substitute pListStrE for pListStr. pListStr contains the string
representation of the fileid, so it seemed like the one to use. According to

This is a follow-on to a question I asked yesterday, which was answered by
MRAB. I'm using the Python C API to load the Gutenberg corpus from the nltk
library and iterate through the sentences. The Python code I am trying to
replicate is:
from nltk.corpus import gutenberg
for i, fileid in en
