3. Update vehicle attributes
4. Print out inventory

Here is the code:

1 2 import uuid from datetime import datetime class automobile: 3 4 5 6 7 8 9 def _init__(self,make: str, model: str,color: str,year: int,mileage: int): self._id = uuid uuid1().hex self. make = make self. model = model self. color = color self._year = year self._mileage = mileage self._createdate= datetime.now().strftime("%d-%m-%Y %H:%M:%s") def add_vehicle(self,inventoryobj): inventoryobj.append(self) def remove_vehicle(self, inventoryObj): inventoryobj.remove(self) def set_make(self,make: str): self._make = make 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 def set_model(self,model: str): self._model = model def set_color(self,color: str): self._color = color def set_year(self, year: int): self._year = year def set_mileage(self,mileage: int): self._mileage = mileage def __str_(self): return '{},{},{},{},{},{},{}'.format(self._id, self._make, self._model, self._color, self._year,self._mileage, self._createdate) PROBLEMS OUTPUT DEBUG CONSOLE TERMINAL 41

import uuid
from datetime import datetime


class automobile:

    # setting up the constructor with default aruguments
    # default argument can be removed, the all the parameter 
    # should be passed with constructor invocation.
    def __init__(self, make="", model="", color="", year=0, mileage=0):
        self.__id = uuid.uuid1().hex
        self.__make = make
        self.__model = model
        self.__color = color
        self.__year = year
        self.__mileage = mileage
        self.__createdate = datetime.now().strftime("%d-%m-%y %H:%M:%S")

    def add_vehicle(self, inventoryObj):
        inventoryObj.append(self)
    
    def remove_vehicle(self, inventoryObj):
        inventoryObj.remove(self)

    def set_make(self, make):
        self.__make = make
    
    def set_model(self, model):
        self.__model = model
    
    def set_color(self, color):
        self.__color = color

    def set_year(self, year):
        self.__year = year

    def set_mileage(self, mileage):
        self.__mileage = mileage

    def __str__(self):
        return '{}, {}, {}, {}, {}, {}, {}'.format(self.__id, self.__make, self.__model, self.__color, self.__year, self.__mileage, self.__createdate)
    

# creating an empty list to store vehicle content
myVehicleList = []

# creating a vehicle object and printing the same
tom_car = automobile("Toyota", "Fortuner", "White", 2014, 10)
print tom_car

# creating an empty object and adding details using the set functions
bob_car = automobile()
bob_car.set_make("Mercedes")
bob_car.set_model("4matic")
bob_car.set_color("black")
bob_car.set_year(2019)
bob_car.set_mileage(8)
print bob_car

# adding the created objects to the list
tom_car.add_vehicle(myVehicleList)
bob_car.add_vehicle(myVehicleList)

# printing the list elements
print myVehicleList[0]
print myVehicleList[1]
