Question

I have a C++ program:

class X
{
    private:
        int a;
    public:
        int func(char *str);
};

Now I want to call the function func in my Python program. How can I do it?

I have successfully called C functions from my Python program using ctypes.
However I can’t seem to figure out how to call functions defined inside C++ objects.

I have already worked with ctypes, so I would like to figure out how to accomplishing it that way. However I’m open to other techniques. Also my project puts a constarint that I am not supposed to use wrapper function in my C++ program.

You tagged the question ctypes, but you cannot instantiate a C++ object directly from ctypes. You can wrap the C++ object in a C interface and then use ctypes. Or you could write a Python extension module which could include C++ code.
