I created a dictionary with the Python C API and assigned two keys and values:
PyObject* this_dict = PyDict_New();
const char *key = "key1";
char *val = "data_01";
PyObject* val_p = PyUnicode_FromString(val);
int r = PyDict_SetItemString(this_dict, key, val_p);
// Add another k-v pair
key = "key2";
val = "data_02";
val_p = PyUnicode_FromString(val);
r = PyDict_SetItemString(this_dict, key, val_p);
I need to retrieve the entire dictionary to be passed to a library function
that expects a dictionary. I used PyDict_Items:
PyObject* pdi = PyDict_Items(this_dict);
PyObject* str_untagd = PyObject_Str(pdi);
PyObject* repr_utd = PyObject_Repr(str_untagd);
PyObject* str_utd = PyUnicode_AsEncodedString(repr_utd, "utf-8", "~E~");
const char *bytes_d = PyBytes_AS_STRING(str_utd);
printf("REPR_UnTag: %s\n", bytes_d);
but as the docs say (https://docs.python.org/3.8/c-api/dict.html), that returns
a PyListObject, not a dictionary enclosed with curly braces:
[('key1', 'data_01'), ('key2', 'data_02')]".
My question is, how can I get the dictionary as a dictionary type, enclosed
with curly braces. I found PyObject_GenericGetDict
(https://docs.python.org/3.8/c-api/object.html) but I haven't found any
documentation or explanation of how it works.
Is PyObject_GenericGetDict what I need, or is there another way to do it?
Thanks,
Jen
