This is a python File
Create a program that presents a menu with these options:
-
Add product
-
Sort by quantity (low to high)
-
Print Inventory
-
Quit
Read the initial product information from a text file.
Remember to ask the user to enter the filename & make sure it exists! The program should NOT product an error if the file isn’t there!
Store the product information into a DICTIONARY called prodDict. The dictionary should map the productID (the key for the dictionary) to a LIST that contains description, unitPrice, and quantity.
The text file will be structured as shown below, where each line contains the product id, product description, unitPrice and quantity.
NOTE: Each entry on the line is separated by a comma and a space.
Example textfile:
111, arm chair, 99.99, 5
444, desk, 10, 40
777, lamp, 20, 5
333, credenza, 50.98., 20
222,bassinet , 5.59, 10
Example of the empDict after the information shown has been readd and stored:
{ 111: [“George Gray”, 10, 40], 222: [“Amy Abrahmson”, 10,30], 333: [“David Dell”, 10, 42], 444:[“Bob Brown”,5,40] }
The program must contain the following functions – make sure the name of the function is exactly as shown and that it accepts the parameters shown:
-
createMenu(optionList, menuTitle) returns a string
-
getValidChoice(numOptions, menuStr) returns an integer
-
addProduct(prodDict) doesn’t return anything –
dictionaries are passed on a two-way street (by reference)
asks the user to enter id, description, unitPrice, and quantity
stores the information into the prodDict -
printReport(prodDict) doesn’t return anything. Simply prints a report
calculates totalCost -
at the end of the report, prints the grand total showing the value of all of the products in the inventory
Example of the report for the data shown:
111, arm chair, 90.99, 5
444, desk, 10, 40
777, lamp, 20, 5
333, credenza, 50.98., 20
222,bassinet , 5.50, 10
Product Roster
ID Description Unit Price Quantity TotalCost
====================================================================
111 arm chair $99.99 40 $ 499.95
444 desk $10.00 40 $ 400.00
777 lamp $20.00 5 $ 100.00
333 credenza $50.98 20 $1019.60
222 bassinet $ 5.50 10 $ 50.00
Grand Total: $2069.55
Example of the report for the data if option 2 was selected (sort by quantity):
