Exercise $2$: Programming

The retail company $$Grocery$4$ALL$$ demands a new booking system that keeps track of their inventory,

revenue, and costs regarding their business operations.

Now it$$s your task to provide a system that is capable of handling the following tasks:

$$ Create an inventory of products entailing ID$,$ name, quantity, purchasing price, and selling price

$(10$ different products should be a good starting point$).$

$$ Show Inventory: Display the inventory containing all products.

$$ New products: Add new products to the inventory.

$$ Selling products: Sell products from the current inventory.

$$ Restock products: Increase the stock of current products.

$$ Show the last transactions.

$$ Calculate the total revenue, total value of the inventory, total costs, and total profit.

Interaction:

$$ Your program should ask the user what to do next. So whether a new product should be added,

a given product should be restocked, or sold, or calculations should be provided.

$$ Regarding calculations you should be able to choose between the total revenue, the total value

of the inventory, the total profit, or the total costs.

$$ Also the inventory value should be able to be displayed for specific product IDs.

$$ Adding products, restocking products, and selling products are considered transactions.

$$ Costs do occur whenever a transaction $($add product, reorder product$)$ is processed.

$$ Revenue is generated whenever a product is sold.

$$ Revenue & costs start with a value of $0$ and are updated with every transaction.

$$ The program shuts down gracefully without any error messages. Error handling is expected.

$$ For this task you can use the following languages: PythonPlease attach all relevant code and files as a zip directory to your MMT application.

Please annotate each line of code with a comment explaining its purpose. Each method should have

documentation on what it does, how it works, and what parameters are expected. The program

should be standalone and executable from a standard computer with a minimal amount of

dependencies $($Preferably it can be run from one single data file or $.$exe file$).$ The interaction can be

via a graphical user interface or a terminal. The selection of the interaction method does not

influence our evaluation of your code
