- PYTHON: For remote access, it’s often better to use a Command Line Interface (CLI), rather than a Graphical User Interface (GUI). A CLI does not use a mouse. However, a program can interact with the user via a menu driven interface. In this assignment, you will implement a menu driven interface for maintaining a list of guests. You will also validate user input to make sure that the name entered is not already in the list. Since some of the objectives of this assignment include demonstrating your proficiency with for loops, lists and the 'in' operator, please be sure to do the following: use the list sort() method to sort your list use a for loop to display each element in the list be sure to create the list with three items already in it use the title() string method for title capitalization Not that all of the bullet items above are included in the Week 4 Exercises, including Supplemental Exercise 4, which is not in the book but is in this week's Canvas module. Your program should…Python: Write a code snippet that imports the tkinter library and creates a new window object root. Add a label widget to the window object root with the text "Hello, World!". Write a code snippet that adds a button widget to the window object root with the text "Click me!", and binds the button to a function button_click() that prints "Button clicked!" to the console. Hint: You may find the Label, Button, and command attributes in tkinter useful for completing parts 2 and 3 Note: For each part of the question, make sure to provide clear instructions and examples for the code snippets. Also, make sure to test your code snippets to ensure that they work as intended.Could you kindly explain what the back button does and how it relates to the information that is kept in the back stack? Thank you.

Minimum requirements: Use at least one layout pane to organize and contain nodes (e.g. Pane, Stack Pane, Flow Pane, Grid Pane, Border Pane, HBox, VBox) Use at least two graphics elements (e.g. shapes or images). Make some of your shapes filled and others unfilled. Both shapes must be different. Use at least three JavaFX User Interface (UI) controls (e.g. Label, Button, Check Box, Test Field, Text Area, Combo Box, List View, Scroll Bar, Slider. At least two of the three must be different. Use at least two common “set” properties or methods for nodes (e.g. setTitle (for Stage), setFill or setFont (for Text), setValue (for ComboBox) Use at least two common “get” properties or methods for nodes (e.g. getValue (for ComboBox), getText (for TextField)) Handle at least one user generated event (e.g. button click, mouse click, etc.)I need help coming up with more detailed comments for each section of code, separating the logic into different classes or methods to improve code modularity and readability and in the "fileMenu" ActionListener, the catch block only prints the stack trace and shows a message dialog. It would be better to provide more informative error messages to the user, indicating the cause of the error. Also the frame size is set to 400x400 pixels using the numbers directly in the code. What would constants or variables to represent these numbers look like?
