develop a console$-$based $($character$-$based, not GUI$)$ system that records information about vehicles. The vehicles we will deal with are of the car, truck and SUV type. The test program for the application is partially written: see link to file below.

The program must be developed step by step and in the first part you must create the following classes:

The class Vehicle with the following characteristics:

brand

year model

mileage

price

A constructor that initializes all variables.

the method $\_\_$str$\_\_$ which prints info about all members in the class.Car which inherits from Vehicle has the following additional data number of doors. A constructor that initializes all variables.

Override the $\_\_$str$\_\_$ method which additionally prints data relevant to the Car class.

Truck that inherits from Vehicle has the following additional data

wheel drive, $2$ or $4$WD

A constructor that initializes all variables

Override the $\_\_$str$\_\_$ method which additionally prints data relevant to the Truck class.

SUV that inherits from Vehicle has the following additional data

passenger capacity

A constructor that initializes all variables

Override the $\_\_$str$\_\_$ method which additionally prints data relevant to the SUV class.

Take car$\_$truck$\_$suv$\_$demo.py as a starting point

enter code for menu items $1-3,$

In the second part of the assignment, you must add the following:

Enter code for menu item $4.$

One should be able to search the overview for a brand and have all vehicles of this brand printed out

When the program starts, all vehicles must be read from the file, if the file does not exist, the list of vehicles is set equal to an empty list.

When the program ends, all vehicles must be sorted and written to a file $($pickle $/$ unpickle$)$

Add code to catch exceptions that the program may throw, typically errors in user input and errors in file handling
