I have a big .cpp file with a lot of classes. I need to import one specific class in this file into python and be able to use it there. I provide a sample main function in the file which a creates an object of this class(named "Nuclei", just scroll down or search for it within the file) and shows how it is used. It is a really simple class but I don't know hot to import it in python. I attach the file so you can play around with it. If you are capable of roughly reproducing my example main function from within python, that is create a Nuclei object and call one of its functions, then the work is automatically yours. Have in mind that I use mac and linux so the solution must be unix compatible.
With my own software product, I have a native Python and Java interfaces to all the library functions. I have a great deal of experience with this.
