Microsoft Word - HA2_spec.docx Homework Assignment - 2 Due: 3/14 11:59PM Topics: Branching, for and while loop, Sequence, Basic I/O Problem description: Write a python application to simulate a simple apps store. The purpose of this assignment is to gain experience in python’s loop (while and for) structure, condition structure, sequence and basic I/O. Design solution: The program will have a global apps list of all apps which is provided in the template file. Each of the item in the list contains a name of the app and its price, name and price are separated by a colon ( : ). The program will have a menu for actions available to the customer. A customer will be able to choose the following options from the menu: 1. display all apps: Display all the apps in the master apps list with its price information. You need to use a for loop to iterate over the apps list, separate the name and price and display the information as shown in sample I/O. Directly printing the list will deduct points. 2. add app to the shopping cart: Customer will only be able to add an app if the name is in the master apps list. Once added, the name and its price need to be added to a shopping cart list, the information - name and price - needs to be separated (as in master list) by any delimiter of your choice (like: colon, space, dash etc). Display the shopping cart list after adding an item. 3. delete an app from cart: Customer will enter the name of the app and the program will look for the app in the shopping cart list to be deleted from. Display the shopping cart list after deletion. 4. check out: Display the list of the apps and their individual price that are being selected by the user, then display the total price the shopping cart. Again, you need to use a for loop to iterate over the shopping cart list, separate the title and price and display the information as shown in sample I/O. Directly printing the list will deduct points. 5. exit/terminate the program. Notes: • The customer shopping cart list should be implemented as a separate list. Any addition/deletion of items should be done in this list. apps list should not be modified. • The program needs to handle uppercase and lowercase letter. Customer can enter the name that can have all small letter but the program should still be able to find the app if in the global apps list. You can use str.lower() – converts all letters to lower case or str.upper() – converts all letters to uppercase. Sample I/O: A sample I/O is provided to see how the program works. You need to use formatting function to properly display the information. Please note sample I/O is provided to clarify what to be expected from the program. You may change the language/interface but the program needs to display the information as shown: *********** Welcome to mini app store *********** Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 1 ******* List of apps ******* Name--Price --------------------------------- Weather channel--$1.99 Bubble Shooter--$0.99 Gallery Pro--$1.09 Scanner Pro--$2.99 Voice Recorder--$3.99 Peak Finder--$4.99 ********************** Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 2 Enter app name to add to cart: weather channel *********** Your Cart *********** Name--price Weather channel--$1.99 ********************** Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 2 Enter app name to add to cart: scanner pro *********** Your Cart *********** Name--price Weather channel--$1.99 Scanner Pro--$2.99 ********************** Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 3 Enter app name to delete from cart: scanner pro Scanner Pro deleted from cart *********** Your Cart *********** Name--price Weather channel--$1.99 ********************** Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 4 Your cart: Weather channel--1.99 Your Total: 1.99 Available options: 1: Display apps 2: Add apps to my cart 3: Delete an apps from cart 4: Checkout 5: Exit Enter option: 5 *********** Thanks for shopping with us *********** >>> Submission: 1. All submission will be via BlackBoard. 2. Acceptable resources to use for this assignment are: class resources, instructors and python language library and references. 3. The codes and pseudocode need to be written in the firstname_lastname_HA2.py file. Please change the name and header of the file before submission. Grading Rubrics: Excellent Average Needs Improving Points Submission Details Both file name and file header meet stated spec. Either file name is incorrect or file header is missing sections/details. Both file name and file header are missing or are incorrectly implemented. ___/2 Code readability Comments demonstrate which line is related to which step of pseudocode and user- defined names clearly demonstrate what they represent. Comments generally demonstrate which line is related to which step of pseudocode and user- defined names generally demonstrate what they represent. Comments and pseuducode are unrelated and user- defined names provide no insight into the referenced data. __/3 Control structure Control structures are implemented correctly. Control structures are generally implemented with minor flaws. Control structures are significantly flawed, or missing. ___/5 While and for loop Loop is implemented correctly with correct loop variable initialization and terminating condition Loop is implemented generally with minor flaws in correct loop variable initialization and/or terminating condition. Loop is significantly flawed, or missing. ___/10 I/O All specified standard input and output are implemented including data conversion. All specified standard input and output are generally implemented with minor flaws and/or no data conversion. Specified standard input and output are not implemented and conversion is missing. ___/5 Overall Score ___/25
