infoemation technologySchool of Science, Engineering and Information Technology	 ITECH1400 – Foundations of Programming – SEM3/18 School of Science, Engineering and Information Technology ITECH1400 - Assignment 1 – Recycling Machine Due Date: 5pm, Friday of Week 7 This assignment will test your skills in designing and programming applications to specification and is worth 20% of your non-invigilated (type A) marks for this course. This is an INDIVIDUAL ASSIGNMENT – and while you may discuss it with your fellow students, you must not share designs or code or you will be in breach of the university plagiarism rules. This assignment should take you approximately 20 hours to complete. Assignment Overview You are tasked with creating a text-based program for simulating a Recycling Machineusing the Python 3 programming language. The assignment is broken up into four main components: 1.) Design and model two classes:RecyclableItemand RecyclingMachine, 2.) Create an activity chart which describes the behaviour of the Recycling Machine system,  3.) Create acomputer program that allows a user to enter items that are able to be recycled into a machine.  During the process the machine prompts the user for the type of item to be recycled and how many they have to enter. The machine keeps track of the number of each of the different itemsand keeps track of the total amount to pay the user until they indicate that they are finished. When they stop adding items, print out a receipt and given them the amount of money owing. The receipt should contain the following: a. A listshowing how many of each item has deposited and the cost of each item. b. The total amount provided for each item c. The total money received. 4.) Finally, explain and integrate some code into your Recycling Machine program that keeps track of how many items of each type are in the machine, and, if the machine is full, makes deposits of that item type unavailable. You machine should have at least 4 different products, and allow up to 50 of each product.  Your submission should consist of one document containing the first two parts of the assignment, and three Python scripts that implement the computer program (recyclingmachine.py, recyclableItem.py and main.py). The main.py script runs the main logic of the program and will use instances of the RecyclingMachineand RecyclableItemclasses to simulate depositing into a Recycling Machine. You are provided with a Microsoft Word template to help you complete the first two parts of this assignment. Towards the end of this document you will also be provided with the output of a simulated run of the completed computer program which may help you with this assignment. Assignment Part 1 Details – Class Design Think of a product that you can recycle that you might want to be able to deposit into aRecycling Machine, like maybe an empty soft drink can.  Start by listing all the properties of that object that you can think of – try to come up with at least tengeneral properties of aRecyclableItemand write these down in your Assignment_Part_1_Microsoft Word document, provided for download in the assessment section of your Moodle shell. Next, use the process of abstraction to cut the number of properties back to only ‘key’ properties – write these down in the next section of your Word document. Take a look at the week 2 lecture slides if you need a reminder on how to go about this. Now, fill in the class diagram for your Item class in the Word document template provided. Your RecyclableItemclass does not have to have any methods (i.e. functions) associated with it to perform any actions other than a constructor which takes and set the key properties that you’ve identified. Next we’ll move on to RecyclingMachine class – think about what information the Recycling Machine has to keep track of to allow you to successfully deposit an item to be recycled. There will only really be three key properties that the RecyclingMachine cares about, and the RecyclingMachineclass should have the following five methods available: 1) A default constructor that takes no arguments and initialises a new object and its properties, 2) accept_product(), 3) select_product() 4) payout(anAmount) 5) print_receipt(). Fill in the class diagram for the RecyclingMachine class in the Word template, and that’s the first part completed! Assignment Part 2 Details – Activity Flowchart Using either the online website https://draw.io (preferred), or the applications Visio or Powerpoint – create an activity diagram of how the program should operate to successfully enter their money, buy one or more products, provide change and print a receipt for the user. Make sure to use the correct symbols in your diagram for starting, processes, decisions/branches, and ending the process. Although you may be familiar with how a Recycling Machine works, if not then you can always look onlineRecycling Machine. Don’t worry about taking payment to debit or credit cards, our RecyclingMachine will only provide cash. Once you have completed your activity chart, add it to your assignment template document. Assignment Part 3 Details – Software Implementation You are free to implement the software however you see fit, however the functionality of the software should be able to match the following output. Note that in the below run of the program I have ‘hard-coded’ a small number of RecyclableIteminstances so that products which exist can be purchased – in your code you should do the same. Your program does not have to have the facility to add new recyclable items – just define a few and use them as demonstrated below. If the final option of STOP is chosen, the program should print the receipt and ask the user if they want to start again or quit. Example Program Output Balance: $0.0. Please select a product: (Can, Bottle, Paper, Stop): Can How many cans do you have?:3 Please place 3 cans into machine. Can accepted Can accepted Can accepted You added 3can(s) for $0.20 each. You have $0.6. Balance: $0.6. Please select a product: (Can, Bottle, Paper): Bottle How many bottles do you have?:1 Please place 1bottle into machine. Bottle accepted You added 1 can(s) for $0.50 each. You now have $1.10. Please select a product: (Can, Bottle, Paper): STOP ----- Final Receipt ----- 3 Can(s)				$0.6 1 Bottle(s)			$1.0 Number of items	4 Amount paid:		$1.6 Thank you for recycling at FedUni! (N)ext customer, or (Q)uit? q >>> Part 4 – Code Explanation and Use You are provided with the following two functions which you should 1. Analyse to determine what they do & provide documentation comments for, and 2. Incorporate into your final program solution.  Wherever there is a # followed by some underscores in the code below, you should write a short comment explaining what the below section of code is doing, and if there is space why it is doing it. Do part 1 of the above in the provided assignment 1 template document, rather than here! # Function to: ___________________________ defget_float(prompt): # ____________________________________     value = float(0.0) # ____________________________________ while True: try: # ____________________________________ value = float(input(prompt)) # ____________________________________ if value _.zip Obviously replace  and
