dot	Call Python function	70

pkpy uses a variant of the Vectorcall protocol (PEP 590).

There are 2 methods for calling a python function.

• PyObject* VM::call(PyObject* obj, ...)
• PyObject* VM::call_method(PyObject* obj, StrName name, ...)

For example, to create a dict object,

PyObject* tp = vm->builtins->attr("dict");
PyObject* obj = vm->call(tp);	// this is a `dict`

And set a key-value pair,

vm->call_method(obj, "__setitem__", VAR("a"), VAR(5));
PyObject* ret = vm->call(obj, "__getitem__", VAR("a"));
std::cout << CAST(int, ret) << std::endl; // 5
