these files are used for creating mvc style professional code from simple class in python language.
written in easy to understand way. just save these files into your project folder ,
either overwrite model view controller files or create subclasses and extend those classes
it a way of writing code .it is a way to create a professional or easly maintainable and easy to understand code we should seperate code into 3 things.called model view and controller. it means * we must start execution from controller. * controller will start graphical user interface (view functions) * it will also start core backend code ( model functions). * we should not call model functions from view and we should not call view functions from model. * controller can call view and model functions. so they can communicate if you implemented this basic code then it automaticaly becomes a professional code
mvc.py it contain starting point .the main code model.py contain backend code or code which uses lowlevel api . view.py contains graphical user interface controller.py it contain code responsible for managing model and view.
