For this task, save your work in statspeak.py As we have seen in lecture, a class provides a means to make code and data live (conceptually) in the same place. For this task, you'll implement a class DataFrame that maintains a collection of data items inside self.items, which you keep as a list of floats, and provides the following operations: 1. Upon creation (remember that _init___ function?), the collection is empty. 2. A class method def add(self, x) will add either x or the members of x to the list self.items. Here x is one of the following: (1) a number, (2) a list, or (3) a tuple. If x is a number, it is added to the list directly. If x is a list or a tuple, its members are individually added to the list.

Write a program that allows two players to play tic-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object.Include a 3-by-3 two-dimensional array, as a private member variable, to create the board.If needed, include additional member variables.Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move.Add additional operations as needed.
A for construct is used to build a loop that processes a list of elements in programming. To do this, it continues to operate forever as long as there are objects to process. Is this assertion truthful or false? Explain your response.
The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -…
5. Complete the class code below and include a method named partition which takes an integer array and a partition integer as parameters and then partitions the original array into two new arrays where elements of the first array are all less than or equal to the partition integer and the second array are all greater than the partition integer. The method should print the original array, followed by the lower partition and finally the upper partition. Nothing should be returned by the method. For example, given int[ ] arr = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15} a method call to partition(arr, 11) should output: %3D [1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15] [1, 5, 6, 7, 11] [15, 16, 31, 39, 45, 72] public class Partition { public static void main(String[] args) { int[] arrayToPartition = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15}; %3D int partitionNumber = 11; partition(arrayToPartition, partitionNumber); } /l your method code here } // end of Partition class

In C++ Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!
