from tkinter import * # Import all definitions from tkinterclass WidgetsDemo:    def __init__(self):        window = Tk() # Create a window        window.title("Widgets Demo") # Set a title        # Add a check button, and a radio button to frame1        frame1 = Frame(window) # Create and add a frame to window        frame1.pack()        self.v1 = IntVar()        cbtBold = Checkbutton(frame1, text = "Bold", variable = self.v1, command = self.processCheckbutton)        self.v2 = IntVar()        rbRed = Radiobutton(frame1, text = "Red", bg = "red", variable = self.v2, value = 1, command = self.processRadiobutton)        rbYellow = Radiobutton(frame1, text = "Yellow", bg = "Yellow", variable = self.v2, value = 2, command = self.processRadiobutton)        cbtBold.grid(row = 1, column = 1)        rbRed.grid(row = 1, column = 2)        rbYellow.grid(row = 1, column = 3)        # Add a label, an entry, a button, and a message to frame2        frame2 = Frame(window)        frame2.pack()        label = Label(frame2, text = "Enter your name: ")        self.name = StringVar()        entryName = Entry(frame2, textvariable = self.name)        btGetName = Button(frame2, text = "Get Name", command = self.processButton)        message = Message(frame2, text = "It is a widgets demo")        label.grid(row = 1, column = 1)        entryName.grid(row = 1, column = 2)        btGetName.grid(row = 1, column = 3)        message.grid(row = 1, column = 4)        #Add text        text = Text(window) # Create and add text to the window        text.pack()        text.insert(END, "Tip\nThe best way to learn Tkinter is to read ")        text.insert(END, "these carefully designed examples and use them ")        text.insert(END, "to create your applications.
