Hi Thanks for the reply, I have tried boost::python::object, I am able to access individual list variable send from python also returning successfully to python. But I need these object value to int, from there I can use further. So can u suggest me how to access individual array elements as an int.

Hi,

I have been using boost python for one of my application. In the same I have to send list from python to boost wrapper. Ex:.

...

From python.

a = [1, 2, 3, 4] test(a);

In wrapper my C++ fucntion should be like below:

void test(list a) { list processing. }

I tried similar way, but getting an signature error. I need a help on how to send list from the python, so that can access each element of list in C++ wrapper.

Thanks and Regards, Guru

Is "list" above "boost::python::list"? If not, you might try that. If so, you might try replacing it with "boost::python::object"

HTH,
