Jervis Whitley <jervi...@gmail.com> added the comment:
in _csv.c, the check is done here:
lineobj = PyIter_Next(self->input_iter);
if (lineobj == NULL) {
/* End of input OR exception */
if (!PyErr_Occurred() && self->field_len != 0)
PyErr_Format(error_obj,
"newline inside string");
return NULL;
}
if (!PyUnicode_Check(lineobj)) {
PyErr_Format(error_obj,
"iterator should return strings, "
"not %.200s "
"(did you open the file in text mode?)",
lineobj->ob_type->tp_name
);
Py_DECREF(lineobj);
return NULL;
}
So the returned lineobj is a bytes type and then the PyUnicode_Check
throws the error.
