Python-OOP-static-varaible

Create class SavingsAccount. Use a static variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBalance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12. This interest should be added to savingsBalance. Provide a static method modifyInterestRate that sets the annualInterestRate to a new value. Write a program named SavingsAccountTest to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest and print the new balances for both savers. Then set the annualInterestRate to 5%, calculate the next month’s interest and print the new balances for both savers.

Python-OOP---1

Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables‐a part number (type String), a part description (type String), a quantity of the item being purchased (type int) and a price per item (float). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a float value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a test program named InvoiceTest that demonstrates class Invoice’s capabilities.

Python-Linked-list

Problem 1 : In the LinkedList class, add a method remove(n) to remove the specified node n from the list and return its element. You may assume the linked list contains the specified node. Then, add a swap_head_tail() method to swap the head and tail nodes (not just elements) in the linked list and a random_remove() method to randomly remove a node from the linked list and return its element. Problem 2 : Given a LinkedList of letters s, write the following functions: β€’ join(s) to join all the letters together in the linked list and return the joined string. β€’ remove_duplicate(s) to remove all the duplicate letters, join all the unique letters together, and return the joined string, for example, if the input linked list is β€˜a’ β†’ β€˜c’ β†’ β€˜b’ β†’ β€˜a’ β†’ β€˜a’ β†’ β€˜c’ β†’ β€˜d’, your method should return β€œacbd” or β€œbacd”. β€’ count_vowels(s) to return the number of vowels in the linked list. Problem 3 : Given two sorted SinglyLinkedList of integers, write a function β€’ merge2lists(linked_list1, linked_list2) to merge the two linked lists into a new sorted linked list and return it For example: Before merging: list1: 2β†’11β†’19β†’21β†’23β†’24 list2: 3β†’9β†’15β†’16β†’22 After merging: 2β†’3β†’9β†’11β†’15β†’16β†’19β†’21β†’22β†’23β†’24 Problem 4 : In the DoublyLinkedList class, add the following public methods: β€’ get_first() to return the first node (not the header) in the linked list β€’ get_last() to return the last node (not the trailer) in the linked list β–ͺ contains(e) method to return true if the linked list contains a specified element e, false otherwise β–ͺ add_before(e, n) to insert the specified element e before that specified node n β–ͺ add_after(e, n) to insert the specified element e before that specified node n β–ͺ You may assume the linked list contains the specified node for add_before() and add_after()

Python-OOP-inheritance

1. Create a super class called Car. The Car class has the following fields and methods. int speed; float regularPrice; str color; float getSalePrice(); 2. Create a sub class of Car class and name it as Truck. The Truck class has the following fields and methods. int weight; float getSalePrice(); # If weight>2000, 10% discount. Otherwise, 20% discount. 3. Create a subclass of Car class and name it as Ford. The Ford class has the following fields and methods int year; int manufacturerDiscount; float getSalePrice(); # From the sale price computed from Car class, subtract the manufacturer discount. 4. Create a subclass of Car class and name it as Sedan. The Sedan class has the following fields and methods. int length; float getSalePrice(); # If length > 20 feet , 5% discount, Otherwise, 10% discount. 5. Create MyOwnAutoShop class which contains a main() method. Perform the following within the main() method. a. Create an instance of Sedan class and initialize all the fields with appropriate values. Use super(...) method in the constructor for initializing the fields of the superclass. b. Create two instances of the Ford class and initialize all the fields with appropriate values. Use super(...) method in the constructor for initializing the fields of the super class. c. Create an instance of Car class and initialize all the fields with appropriate values. Display the sale prices of all instance.
