A clothing store maintains inventory on items in their warehouse. All clothing items come in 4 standard sizes, S, M, L, XL. There are 2 files that stores the items and inventory. The first file contains the item code and description and the second file contains the inventories of the various sizes. See appendix A for the contents of the 2 files. A program is required to track the movement of inventory in and out of the warehouse. (a) Write a function loadItems (filename) with a string filename as parameter. The function reads in the contents from items.txt, populates a dictionary and returns the dictionary. The key of the dictionary is the item code and the description is the value. Based on the contents of the file given, the dictionary should look like: items={'C10': 'Jogging pants', 'C01': 'Airism T shirt', 'C03': 'Socks', 'C05': 'Polo T', 'C11': 'Shorts'} Ensure all blanks and newline \n characters are stripped. (5 marks) (b) Write a function load Inventory(filename) with a string filename as parameter. The function reads the contents from inventory. txt, populates a dictionary and returns the dictionary. Based on the contents of the file given, the dictionary should look like: {'C85':[18,10,5,4], 'CO1':[9,20,10,5], 'C11':[10,20,18,1], 'C03': [0,0,10,0]} (c) Write a function displayInventory (items, inventory) where the first parameter is the item dictionary, and the second parameter is the inventory dictionary. Display an inventory report, sorted by item code, in the following format: Inventory Report C01 Airism T shirt SO M 20 L 10 XL 5 Total quantity=35 C03 Socks SO Me L 10 XL 0 Total quantity=10 (Only a sample of 2 items shown.) Note: Only partial credit will be given if selection statements are used for this function. (5 marks) (d) Write and develop the main function that has a menu as follows: 1. Add new item ● 2. Update inventory 3. Inventory report 4. Exit Enter option : The main function loads the 2 dictionaries using the functions in part (a) and (b) before the menu is displayed. The description of each of the menu options is as follows: Option 1 Add new item This option allows for adding of new items in the warehouse. Prompt for item code. Ensure that item code is not a duplicate of the existing item codes. This is followed by the description and the 4 sizes. A sample input is as follows: Enter item code: C11 Item code already exists! Enter item code: C88 Enter description: Pullover Enter the quantities (S, M, L, XL): 12, 10, 5,0 Inventory added! Enter item code: <Enter> Note the input requirements: Item code may already exist, display an error message and prompt for the code again. ● This option should allow for many items to be added. Use <Enter> key as indication of end of input. Quantities for the sizes are integers entered with commas in between. No validation of the digits and format is required. Option 2 - Update Inventory Input the item code. If the item exists, the description and existing quantity is displayed, followed by the size and quantity. This quantity is added to the stock level for that particular size. A sample program execution is as follows: Enter item code: C29 Item not found! Enter item code: C11 Item description: Shorts Current inventory (S, M, L, XL): [10, 20, 10, 1] Enter size (S, M, L, XL): XL Enter quantity: 20 C11 size XL quantity updated to 21 If item code is not in the dictionary, display ‘Item not found'. Prompt for item code again. There is no need to validate input for size and quantity. This option allows for only 1 update. It does not prompt for another item code upon successful update. Option 3 - Inventory report Print the complete inventory report as shown in part (c). (10 marks) Appendix A Assume there are no errors in the contents of the 2 files. Items.txt The item code and the description are on separate lines. C10 Jogging pants C01 Airism T shirt C03 Socks C05 Polo T C11 Shorts Inventory.txt The item code and the sizes are separated by : followed by the 4 sizes separated by commas. C05:10,10,5,4 C01:0, 20,10,5 C11:10, 20,10,1 C03:0,0,10,0 ---- END OF ASSIGNMENT ---- A clothing store maintains inventory on items in their warehouse.
