Thank you for reply. Of course, import just a class from the module. The reason of have each class in separate file is that I have a base class with basic functionality  and a lot of derived classes from it with custom functionality for each class. Also,  the program is modular and periodically will need adding some new modules. So, for better organisation of all this stuff I have put them in separate files.
