Can you please help me writing the code for this project in python language using the while looping or if methods. This final project will ask you to write some classes and a function that will process a list of strings and turn that into a list of objects (and aggregate objects). You will have to do the following for this assignment: Create and complete the methods of the item class. Create and complete the methods of theShipmentclass. Create and complete the methods of theItemExceptionclass. Write a main function in a file calledproject5.py. You may complete all three components in a single file, or you may create multiple files as long as you import them correctly. Step 1: Writing Test Cases Ideally, you should write your test cases before you write your code. However, testing objects, such as those of the Shipment class, are more difficult due to their stateful nature. We can no longer test all methods individually, without at least calling the constructor. For this reason, we will not be writing formal test cases for the project; we need a better testing infrastructure, which you will learn about in CS211 if you take it. Instead, we’ve provided a sample test harness inside the driver below. Feel free to modify this harness (by including print statements?) should you need to. You will be creating a Item class with the following methods: A constructor that takes a name, id, and price. The constructor creates these three attributes and sets them to the incoming arguments. Getters for all attributes (getName, getId, getPrice). A to-string method that can be called with str(…), which returns the name of the item, followed by a space, followed by the id, followed by a space, followed by the price. For example, a constructor call of item = Item(‘socks’,12345,’$4.56′) would yield the string ‘socks 12345 $4.56’. You will be creating a Shipment class with the following methods: A constructor that takes an id. The constructor creates this attribute and sets it to the incoming argument. The constructor also initializes an empty list of items. Getters for all attributes (getId and getItems). An addItem method that takes an Item as an argument and adds it to the end of the shipment’s list of items. A to-string method that can be called with str(…), which returns the id of the item, followed by a colon, followed space, followed by a list of all its shipments. The list will open and close with [ and ], and will contain all the items of the shipment, in the order of the list, using their to-string method to append them with commas as the only separator (see the test cases. For example the following object: item = Item(‘socks’,12345,’$4.56′) shipment = Shipment(55555555) shipment.addItem(item) item = Item(‘shirt’,33333,’$14.78′) shipment.addItem(item) would return the string ‘55555555: [socks 12345 $4.56,shirt 33333 $14.78]’.
