- py_is_object(@Term) is semidet
- True when Term is a Python object reference. Fails silently if Term
is any other Prolog term.
- Errors
- -
existence_error(py_object, Term) is raised of Term is a
Python object, but it has been freed using py_free/1.
- Compatibility
- - PIP. The SWI-Prolog implementation is safe in the sense that
an arbitrary term cannot be confused with a Python object and a
reliable error is generated if the references has been freed.
Portable applications can not rely on this.
