Create a script called manageProducts.py. It should allow the user to Create, Read, Update, and Delete products using the framework we have built. Products should have the following fields: id (pk, auto_increment) name description price stock (number in inventory)   - Create the product table as username_products - create a product class from the user class - change the code in app.py to use product class, not user - copy app.py to manageProduct.py, and make changes so you can edit products instead of users. - add additional functionality to manageProducts.py to c,r,u,d - This means adding an if statement for read and delete, also finishing the update

read carefully. object must be passed to method not variables

Class Circle           A Circle will have a radius.  The class will be able to keep track of the number of Circle objects created.  It will also hold the total of the circumferences of all the Circle objects created.          It will allow a client to create a Circle, passing in a double value for the radius into the Circle constructor. If the value for the radius that is passed in is 0 or negative, then the radius will be set to a value of 999.  The constructor should add 1 to the count of the number of Circles created. The constructor should call a method to calculate the circumference and then add the circumference for that object to an accumulator.    In addition to the constructor, the Circle class must have the following methods that return a boolean value:   isCongruent(Circle c) – Compares two Circle objects to determine if they are congruent (radii are equal). isValid() – the radius may not be 0 or negative.  equals (Triangle t) – compares two Triangle objects…

In Java programming. Write the method that will populate the properties of each object.  Assume that you have read the data from a flat file into variables for each property in the class.  customer = new_Customer (); inventory = new_Inventory (); orderHeader = new_OrderHeader (); orderDetail = new_OrderDetail (); invoice = new_Invoice (); shipment = new_Shipment ();   Use one of the object names from above. Write the signature line for this method Write the code that will assign a variable value to one property in the selected object. Be sure variable names use proper naming convention.

Q2: Create a book modelDraw a class diagram to depict a book as specified by the following statement: "A book is made up of several parts, each of which is made up of several chapters."Sections are made up of chapters." To begin, concentrate just on classes and associations.Multiplicity should be added to the class diagram you created.Improve the class diagram by adding the following features:• The book has a publisher, a publishing date, and an ISBN number.• A title and a number are included in a part; a title, a number, and an abstract are included in a chapter; and a title, a number, and an abstract are included in a section.Take a look at the refined class diagram. A title and a number characteristic are included in the Part, Chapter, and Section classes. To factor out these two traits, use inheritance.
