You are tasked with developing a Car Rental Management System for a small auto rental business. The system should read car inventory from a file, allow the user to rent and return cars, update records, and save all changes. This question assesses your ability to work with: 1. Car Data File – cars.txt The file cars.txt contains the car inventory. Each line has the following values, separated by commas: car model, brand, availability car model – string (e.g., Civic, Corolla, Model 3) brand – string (e.g., Honda, Toyota, Tesla) availability – either available or rented Sample cars.txt content: Civic,Honda,available Corolla,Toyota,rented Model 3,Tesla,available Mustang,Ford,available Accord,Honda,rented You may use this example or create your own cars.txt, but it must follow the same format. 2. Class Design (OOP + Inheritance) You must create the following classes: a) Class Car Attributes: model brand availability (string: “available” or “rented”) Methods: __init__ rent_car(self) – sets availability to “rented” if it is currently “available”. return_car(self) – sets availability to “available”. __str__(self) – returns a readable string like: Civic (Honda) – available b) Class ElectricCar (inherits from Car) Inherits from Car. Additional attribute, for example: battery_range (e.g., 250 miles) Overrides __str__(self) to include the extra information, e.g.: Model 3 (Tesla) – available – 250-mile range You may decide which cars are ElectricCar (for example, by model or brand). c) Class CarRentalSystem Attributes: cars – a dictionary where: keys = car model (string) values = Car or ElectricCar objects Methods (minimum): load_cars_from_file(self, filename) Reads cars.txt and fills the dictionary. save_cars_to_file(self, filename) Writes the current car data back to the file. list_cars(self) Displays all cars with brand and availability. rent_car(self, model) Rents the specified car (if it exists and is available). return_car(self, model) Returns the specified car (if it exists and is currently rented). 3. Required Functions In addition to your classes, define the following functions: def list_cars(system): Calls the appropriate method on the CarRentalSystem object to display all cars. def rent_car(system, model): Uses the CarRentalSystem to rent the car with the given model and then saves the updated data to the file. def return_car(system, model): Uses the CarRentalSystem to return the car with the given model and then saves the updated data to the file. def main(): Creates a CarRentalSystem object. Loads data from cars.txt. Repeatedly: Displays a menu of choices: List all cars Rent a car Return a car Exit Asks the user for an option and performs the corresponding action. Saves changes before exiting. 4. Exception Handling Your program must handle the following cases: Missing file (cars.txt) Use try / except FileNotFoundError. If the file does not exist: Inform the user. Allow the user to enter at least one car (model, brand, availability) manually. Store this car in the system and then create a new cars.txt file with this data. Invalid car model If the user tries to rent or return a car that does not exist in the dictionary: Print an error message such as “Car model not found.” Do not crash. 5. Program Behavior Summary When your program runs, it should: Load car data into the CarRentalSystem. Display all cars (model, brand, availability). Allow the user to: Rent a car Return a car Exit Save all changes back to cars.txt when cars are rented/returned and when the program exits. 6. Submission Instructions (Important – Read Carefully) To receive credit for this question: You must upload your .py and .txt file as a separate attachment. Copying and pasting the code directly into the text field is not acceptable. If you do not provide the .py and .txt file you will receive a score of zero for this question.
