Focus on classes, objects, methods and good programming styleYour task is to create a BankAccount class using Python.
Class name
BankAccount
Attributes
__balance float float
__pin integer integer
Methods
__init_()get_pin()check_pin()deposit()withdraw()get_balance()
The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0.get_pin()should return the pin.check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not.deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was…
It is convention that all metmber variables in a Java class are declared to have_____ access so they are not accessible outside the class.
Python Programming
A- Define a class called Vehicle as follows:
The Vehicle class has two instance variables:
name,
max_speed
Define an __init__ function for the Vehicle class that initializes the name and max_speed instance variables
Define get and set methods for each of the name and max_speed variables. You may call them getName, getMax_speed, setName and setMax_speed
Define a __str__ function that prints the name and max_speed of the Vehicle class.
B- Define a class called Car as follows:
The Car class is a subclass of the Vehicle class.
The Car class has an instance variable called number_of_cylinders
Define an __init__ function for the Car class that initializes the name and max_speed and number_of_cylinders instance variables
Please note that the Car class inherits the name and max_speed variables from the Vehicle class and does not redefine them.
Define get and set methods for the number_of_cylinders variable.
Define a __str__ function that prints the name and…

Bank Account Manager Main Menu=========1 – Checking Account2 – Saving Accountx - Exit program Requirements Create the bank account to store a bank customer’s account number and balance. Suppose that account number is of type int, and balance is of type double. Your class should, at least, provide the following operations: set the account number, retrieve the account number, retrieve the balance, deposit, and withdraw money, and print account information. Add appropriate constructors. Every bank offers a checking account. Derive the class checking account from the class bank account (designed in part 1). This class inherits members to store the account number and the balance from the base class. A customer with a checking account typically receives interest, maintains a minimum balance.
