ghment #2 The application should be extendable so that a new search criterion can be added, perhaps as a new class, without having to modify the user interface. For example, a client user can add a new criteria by writing a class and registering it with the system. On adding that class, the new criterion should appear as a new item within the combo box.

14.23 LAB: Dean's list Students make the Dean's list if their GPA is 3.5 or higher. Complete the Course class by implementing the get_deans_list() instance method, which returns a list of students with a GPA of 3.5 or higher. The file main.py contains: . The main function for testing the program. Class Course represents a course, which contains a list of student objects as a course roster. (Type your code in here.) • Class Student represents a classroom student, which has three attributes: first name, last name, and GPA. (Hint: get_gpa() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Dean's list: Henry Nguyen (GPA: 3.5) Sonya King (GPA: 3.9)

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argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful.
