Question

You built your own 3D printer and intend to make a business of printing small parts for customers. After advertising your business on campus, you receive hundreds of emails within the span of a few days - all of which are fellow students asking for quotes on printing their parts. You go through all of the STL files, and record the approximate print time, material use and cost estimates for each as follows: Order 1: Order 2: Print Time: 43 minutes Print Time: 28 minutes Colour: Red Colour: Blue Material: 1.64 feet Material: 0.91 feet Cost: 3.80 $USD Cost: 2.11 $USD Order #: Print Time: ## minutes Colour: ... Material: #### feet Cost: #.## $ USD You've recorded each customer order as shown above and intend to start completing orders next week. Before hand, you want to know the total amount of time the printing will take, the total amount of material for each colour filament that you need to have on hand and the total material costs. Seeing as there are hundreds of orders on file you don't want to do these calculations manually, so you decide to use Python instead. In this assignment, you will be completing the function definition printing(orders), which has been started for you in the code template notebook. This function takes in a list of strings orders, where each element in the list is one line from the orders file, such as: orders = ["Order 1:\tPrint Time: 43 minutes\tColour: Red\tMaterial: 1.64 feet\tCost: 3.80 $USD", "Order 2:\tPrint Time: 28 minutes \tColour: Blue \tMaterial: 0.91 feet\tCost: 2.11 $USD"] You must complete the function definition to satisfy the following requirements: 1. The program computes the following 3 values: a. printTime = the total print time for all orders, stored in a list: [hours, minutes] b. matlused = the total material used for all orders, stored in a list based on filament color: [Red_matlused, Blue_matlused, Yellow_matlused, White_matlused, Black_matlused). Since your filament provider is based out of Canada, you need to provide this measurement in metres (1 metre = 3.28 feet). c. matlCost = the total material cost in $CAD (1 $USD = 1.42 $CAD). d. profit = your estimated profit if you charge 0.25 SCAD/minute of printing and only account for the material cost in your expenses (profit = revenue - expenses). 2. The program returns print Time, matlused, matlCost, and profit as output (done for you in the code given). 3. Your name, Maced, and the date are given in comments in the first Python cell. 4. Your answers to the design questions and test plan are given in the appropriate cells in the Python notebook. 5. Your program MUST have valid Python syntax and it must run without errors. Ensure that your
