How to get reference count of a PyObject from C++?
如何从C ++获取PyObject的引用计数?
There are functions Py_INCREF and Py_DECREF which increase/decrease it, but I haven't found any function which return object's reference count.
有函数Py_INCREF和Py_DECREF增加/减少它,但我没有找到任何返回对象引用计数的函数。
I need it for debugging purposes.

The reference count of each and every object is stored in the PyObject itself, in a variable called ob_refcnt. You can directly access that.
每个对象的引用计数存储在PyObject本身的一个名为ob_refcnt的变量中。你可以直接访问它。
typedef struct _object {
_PyObject_HEAD_EXTRA
Py_ssize_t ob_refcnt; # Reference count
struct _typeobject *ob_type;
} PyObject;
Alternatively, you can use the Py_REFCNT Macro.
或者,您可以使用Py_REFCNT宏。
