Let's say you have file(s)

/file?name?.py

class Module:
     def __init__ (self, my_parameter):
         variable_one = 1

/in a directory, you have no idea what the file is called, but you want 
to make it accessible, you would then:

/import importlib.util as i_utils//
//cwd = os.getcwd()//
//module_folder = cwd + "/pycam/modules/"//
//files = os.listdir(module_folder)//
//menu = self.builder.get_object('menu11')//
//for file_ in files://
//    if file_.endswith(".py") and file_ != "__init__.py"://
//        file_name = file_.strip(".py")//
//        f_path = module_folder+file_//
//        spec = i_utils.spec_from_file_location(file_name , f_path)//
//        module = i_utils.module_from_spec(spec)//
//        spec.loader.exec_module(module)//
//        file_label = file_name.capitalize()//
//        file_label = file_label.replace("_", " ") //
//        menuitem = Gtk.MenuItem.new_with_label(file_label)//
//        menuitem.connect("activate", module.Module, 'pycam')//
//        menuitem.show()//
//        menu.append(menuitem)

/I can't find the original place I got this feature, but Google 'dynamic 
import python3' and you will find tens of links. Or feel free to ask for 
explanation on anything I missed. This code was a copied and pasted from
/https://sourceforge.net/p/pygtk-posting/code/ci/master/tree/src/pygtk_posting.py 
/line 97 with minor changes for Pycam.
