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argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful.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…

Create a class object with the following attributes and actions:
Class Name
Class number
Classroom
Semester
Level
Subject
Actions:
Store a class list
Print the class list as follows:
Class name Class Number Semester
Level
Subject
Test your object:
Ask the user for all the information and to enter at least 3 classes
test using all the actions of the object
print using the to string action
Describe the numbers and text you print. Do not just print numbers or strings to the screen explain what each number represents.

A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively.
