NL Can is a local can-making company that makes cans using an eco-friendly material. Recently a number of new eco-friendly paint companies have started up In the area and they have been placing large orders for paint cans in which to put their eco-friendly paint. NL Coan has asked you to design, Implement and test a Python class, CanOrder, to generate order objects for cans with the following attributtes (Instance variables) and class variables. materlal used for the quantity of cans ordered, and the total cost of the order with appropriate descripthv labels, as shown in the sample output Also Include a main function to test the defined class as follows: • create 2 Canorder objects • print information about each order using the special_ _) method change the height of the can in the second order and print the order ID, the updated height and the updated total cost of the order with appropriate descriptive labels • print the total number of orders with an approprlate descriptive label Class variables: • NooFOrders is a class variable that keeps track of the number of orders created (Initially O): NoOFOrders automatically Increments with each new object created, Ie, when the first object is created, NooF0rders should become 1, when the second object is created, Moof0rders should change to 2, etc • NextOrderlo is a class varilable, Initialized to 100, which is used to generate the orderio number for each order as a sequence of even numbers, starting with 100; 1.e, the first order would have an orderio of 100, the second order created would have an orderiD of 102, etc. Instance variables: • ozdesID Is a unique number identifytng the can order and is set using the NexsOrdezlo class variable • quaneityorderedis the number of cans ordered (default value 0) • sadius is the radius of the can In inches (default value 0.0) • heighe is the height of the can in Inches (default value 0.0) • handie is a True/False value Indicating if the cans in the order should have a handle (True) or not (False) • print the total cost of all the orders (both orders, Including the effect of the changed helght of the second order), with an appropriate descriptive label Call the file contalning your class and main function, nl_cans.py. (default value False) Sample input/output: Ozder ID: 100 Also include the following methods: • a constructor method for the CanOrder class with default values for all 4 parameters (not including the self parameter) • three accessor methods, one to retrieve the ID of the order, one for the radlus, and one for the helght two mutator methods, one to change the radius of the can, and one to change the height of the can a method called getTotalsurfaceirea to compute and return the total surface area of all cans ordered; the formula for the surface area of a can is: 2er- 2arh (note: use the math library to get the constant variable pi and the pow function) • a method called gettoralcoss to compute and return the total cost of the order, where the cost of the material used is half of a cent (S0.005) per square centimetre of surface area and if handles are required. then an extra fifty cents (S0.50) is added for each can • the special _) method to print the Information about the order including the orderio, the radius and the height of the can, the quantity ordered, the handle option (True/False), the total surface area of material used for the quantity of cans ordered, and the total cost of the order with appropriate descriptive -l- -- -- -- a- --------- Can Radsus: 5 em Can Height: 10 cm Quantity Ozdezed: 100 cans Handle Needed? False Total Surface Area: 47123.9 sg.em. Iosal Coss: $235. 62 Order ID: 102 Can Radiu:: 7.5 cm Can Height: 20 em Quantisy Ozdered: 300 cans Handle Needed? True Total Surface Area: 3e8772.09 q. em.

Hello, I am having trouble with this question for my c++ homework. How would I go about having it be declared as a class rather than writing it as  #include <iostream> using namespace std: //# define N 8 I want to implement it as a class so I tried the following class: qColumns (N=8){} I'm stuck here    N-Queens.A Queen on a chessboard can attack any piece in the same column, row or diagonal.The N-Queens problem is to place n queens on a n x n chessboard such that no twoqueens threaten each other.a) Implement a one-dimensional integer array of Queen positions for an 8x8 boardwhere indices represent rows and the values represent columns.For example, this “safe” solution would be {3,6,2,7,1,4,0,5}. . .

Please answer question. This is pertaining to Java programming language 3-20

Use as many advanced python techniques as you can  • Write classes to support the Decrypt and the Rotation algorithms.• Use Bitsets, Bytes, where bit manipulations are needed.• Use Regular Expressions to parse and search strings.• Write any supporting classes necessary to support the Decrypt and Rotation Algorithms.• For example, the Decrypt Algorithm needs support for reading an encrypted file.• The Decrypt class is only responsible for decrypting a character, NOT reading a file ANDdecrypting each character.

Create a python class that holds the following personal data: name, address, age, and phone number. Be sure to include proper accessor and mutuator methods.  There should be modifier class that creates three instances of the class described. One instance should hold the information, and the other two should hold the information of friends/family members.  This problem has been giving me a lot of trouble. Any help is greatly appreciated. Thanks so much!!

PLease help with the following: Consider the following Python code: class A:def f(self): passclass B(A):def f(self): passclass C(A):def f(self): passclass D(B, C): pass Which of the following is correct? a. The above code does not compile. It is an example of diamond problem.b. Class D has ambiguous MRO and therefore is not instantiable.c. The program has compiler error.d. The above code does not compile because Python does not support muliple inheritance.e. The above code compiles and runs with no issue.

in python language In this task, we’re going to be simulating an email message. Some of the logic hasbeen filled out for you in the email.py file.● Open the file called email.py.● Create a class definition for an Email which has four variables:has_been_read, email_contents, is_spam and from_address.● The constructor should initialise the sender’s email address.● The constructor should also initialise has_been_read and is_spam to false.● Create a function in this class called mark_as_read which should changehas_been_read to true.● Create a function in this class called mark_as_spam which should changeis_spam to true.● Create a list called inbox to store all emails (note that you can have a list ofobjects).● Then create the following methods:○ add_email - which takes in the contents and email address from thereceived email to make a new Email object.○ get_count - returns the number of messages in the store.○ get_email - returns the contents of an email in the list. For this, allowthe…

In Python without using super(): Given the base class Book, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a print_info() method that overrides the Book class' print_info() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes.
