Model :business logic Contains all the data manipulated by the system. This can include an interface to an external store, such as a database,typically the model exposes only a public API to the other components
View: display code. The widgets that actually place the information in the user’s view. In wxpython ,pretty much anything in the wx.Window hierarchy is part of the view subsystem.
