I used the following codes and having a problem. When I update the vehicle information, the number I input into vehicle mileage goes to vehicle manufacturing year on the updates. How can I fix this issue?

p.s image is attached

class Vehicle:

id = 1

'''

Constructor Function

Name: Name of the vehicle

Model: Model of the vehicle

Color: Color of the vehicle

Year: Manufacturing year of the vehicle

Mileage: Mileage of the vehicle

'''

def __init__(self, make, model, color, year, mileage) -> None:

self.__make = make

self.__model = model

self.__color = color

self.__year = year

self.__mileage = mileage

self.__id = Vehicle.id

Vehicle.id += 1

# Getter method to access the vehicle id

def getVehicleId(self):

return self.__id

def __str__(self) -> str:

return f" Vehicle Id: {self.__id} Vehicle Make: {self.__make} Vehicle Model: {self.__model} Vehicle Color: {self.__color} Vehicle Manufacturing Year: {self.__year} Vehicle Mileage: {self.__mileage}"

class Automobile:

# Constructor function that creates an empty inventory

def __init__(self) -> None:

self.vehicles = []

# Method to add a new vehicle in the inventory

def addNewVehicle(self, vehicleObject):

print(" Adding a new vehicle with id ", vehicleObject.getVehicleId())

# Check whether with the given id is already available or not

# if already available then print appropriate message and return

# Otherwise add the vehicle to the vehicle list

for vehicle in self.vehicles:

if vehicle.getVehicleId() == vehicleObject.getVehicleId():

print("Vehicle is already there in the inventory")

return

self.vehicles.append(vehicleObject)

print("Vehicle with id " + str(vehicleObject.getVehicleId()) + " has been added to the inventory successfully.")

# Method to remove a vehicle from the inventory

def removeVehicle(self, id):

print(" Removing the vehicle with id ", id)

# Iterate each vehicle from the list

for v in self.vehicles:

# if the id of the current vehicle matches with the given id

# then remove the vehicle and return

# otherwise print appropriate message

if v.getVehicleId() == id:

self.vehicles.remove(v)

print("Vehicle with id " + str(id) + " has been deleted successfully")

return

print("Vehicle with id " + str(id) + " is not present in the inventory.")

# Method to update the attributes of a particular vehicle

def updateVehicle(self, id):

print(" Updating the vehicle with id ", id)

for v in self.vehicles:

if v.getVehicleId() == id:

v._Vehicle__make = input("Enter new Vehicle make: ")

v._Vehicle__model = input("Enter new Vehicle model: ")

v._Vehicle__color = input("Enter new Vehicle color: ")

v._Vehicle__year = input("Enter new Vehicle manufacturing year: ")

v._Vehicle__year = input("Enter new Vehicle mileage: ")

print("Details updated.. ")

return

print("Vehicle with id " + str(id) + " is not present in the inventory. ")

# Method to print each vehicle details in the inventory

def displayVehicles(self):

print(" Vehicles available in the inventory are: ")

for vehicle in self.vehicles:

print(vehicle)

print("------------------------------------------")

def writeToFile(self):

print(" Writing inventory data to the vehicle.txt file")

try:

with open("vehicle.txt", 'w') as file:

for v in self.vehicles:

file.write(v.__str__())

print("Data has been successfully written to the vehicle.txt file")

except:

print("Some error occurred.")

# Creating vehicle objects

v1 = Vehicle('Maruti', 'Alto', 'Black', 2021, 21)

v2 = Vehicle('Maruti', 'Baleno', 'White', 2020, 18)

# Creating Automobile class object

a = Automobile()

# Adding vehicle to the inventory

a.addNewVehicle(v1)

a.addNewVehicle(v2)

a.addNewVehicle(v2)

# Displaying vehicle inventory

a.displayVehicles()

a.removeVehicle(2)

print(" Updated inventory")

a.displayVehicles()

a.updateVehicle(1)

a.displayVehicles()

a.writeToFile()

Output:
