The goal of the project is to design and implement a basic media library system in which administrators (you) can inquire the current inventory, and add or remove items. These items are identified either as books as follows. Each entry in the library can be identified by its media type (Movie or Book), its Title, its Reference, and its Price. A sample media library comprised of 9 items is given in Table 1 11.99 10.I ime Zarathustra aabout by its Author, while a movie media item The project must include three files: 1. Medialtem.py file/module that contains the user-defined type (object data) Medialtem. 2. inventory.py file/module that contains all the necessary functions to operate the inventory 3. media-store.py file containing the main program. At the first execution of the program media-store.py, the output includes a menu containing 9 options: Welcome to BestMedia Mens 1-List Inventory 2-Info Inventory 3-List of All Books 4-List of All Movies 5-Item Description 7-Add Item B-Set Maximun Price O-Exit Once option 0 (for Exit) is selected, the program stops.
