Hi all,
I'm extending C++ with Boost.Python.
At some point I need to call a Python function on an object of unknown
Python type.
I found those 2 solutions, but they seem so simple that they make me wonder
about the dangerosity of doing this (I'm a newbie to Boost.Python):
static void test_func_attr(object pyObj, object arg)
{
pyObj.attr("test")(arg);
}
BOOST_PYTHON_MODULE(my_module)
{
def("test_func_attr", &test_func_attr);
}
Called from :
class MyClass(object):
def test(self,str):
print str
class = MyClass()
test_func_attr(class, "hello")
The second solution is very close:
static void test_func_attr(object pyObj, object arg)
{
object func = pyObj.attr("test");
call<void>(extract<PyObject*>(func), arg);
}
Both are working. Am I doing something wrong here? And which one is the best
(advantage of #1 is that I don't need to know the return type of test())
Thanks in advance
-David
