PyObject* getattr(PyObject* obj, StrName name, bool throw_err=true)

This method is equivalent to getattr in Python. If the attribute is not found, it will return nullptr or throw an AttributeError depending on the value of throw_err.

// create a `int` object
PyObject* obj = VAR(1);

// get its `__add__` method, which is a `bound_method` object
PyObject* add = vm->getattr(obj, "__add__");

// call it (equivalent to `1 + 2`)
PyObject* ret = vm->call(add, VAR(2));

// get the result
int result = CAST(int, ret);
std::cout << result << std::endl; // 3

void setattr(PyObject*, StrName, PyObject*)

This method is equivalent to setattr in Python. It raises TypeError if the object does not support attribute assignment.
