Python Programming1.Write a class named Car that has the following data attributes:(a.) __year_model (for the car’s year model)__make (for the make of the car)__speed (for the car’s current speed)The Car class should have an __init__ method that accepts the car’s year model and make as arguments. These values should be assigned to the object’s __year_model and __make data attributes. It should also assign 0 to the __speed data attribute.The class should also have the following methods:(b). Accelerate: The accelerate method should add 5 to the speed data attribute each time it is called.Brake: The brake method should subtract 5 from the speed data attribute each time it is called.get_speed: The get_speed method should return the current speed
A. Car Class
Create a Python Program where you write a class
named Car that has the following data attributes:
• _ _year_model (for the car's year model)
• __make (for the make of the car)
• _ _speed (for the car's current speed)
The Car class should have an _init_ method that
accepts the car's year model and make as arguments.
These values should be assigned to the object's
_year_model and
make data attributes. It should
also assign 0 to the __speed data attribute.
The class should also have the following methods:
accelerate()
The accelerate method should add 5 to the speed data
attribute each time it is called.
brake()
The brake method should subtract 5 from the speed
data attribute each time it is called.
• get_speed()
The get_speed method should return the current speed.
Next, design a program that creates a Car object then
calls the accelerate method five times. After each call
to the accelerate method, get the current speed of the
car and display it. Then call the brake method…

Your task is to create a BankAccount class.
Class name
BankAccount
Attributes
_balance
float
_pin
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withraw (amount) should check if the amount can be withdrawn (not more than is in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 not.
get_balance () should return the current balance.…

- Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.arrow_forwardFocus on classes, objects, methods and good programming styleYour task is to create a BankAccount class.

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. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class.

- Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object.
