Python: get string representation of PyObject?
If you need just print the object in Python 3 you can use one of these functions:
static void print_str(PyObject *o)
{
PyObject_Print(o, stdout, Py_PRINT_RAW);
}
static void print_repr(PyObject *o)
{
PyObject_Print(o, stdout, 0);
}
Use PyObject_Repr
(to mimic Python's repr
function) or PyObject_Str
(to mimic str
), and then call PyString_AsString
to get char *
(you can, and usually should, use it as const char*
, for example:
PyObject* objectsRepresentation = PyObject_Repr(yourObject);
const char* s = PyString_AsString(objectsRepresentation);
This method is OK for any PyObject
. If you are absolutely sure yourObject
is a Python string and not something else, like for instance a number, you can skip the first line and just do:
const char* s = PyString_AsString(yourObject);
Here is the correct answer if you are using Python 3:
static void reprint(PyObject *obj) {
PyObject* repr = PyObject_Repr(obj);
PyObject* str = PyUnicode_AsEncodedString(repr, "utf-8", "~E~");
const char *bytes = PyBytes_AS_STRING(str);
printf("REPR: %s\n", bytes);
Py_XDECREF(repr);
Py_XDECREF(str);
}
