You have used the Tk(screenName=None, baseName=None, className='Tk', useTk=1) method in your GUI app. TK() is a method to create a main window. To change the name of the window, you can change the className to the desired one. The basic code used to create the main window of the application is: m=tkinter.Tk() where m is the name of the main window object. To create the main window for your GUI application. What will you add to the following code segment? 1. import tkinter as tk 2. 3. window.title("Hello wold") 4. window.geometry("300x300") 5. hello = tk.Label(text="Hello world!") 6. hello.pack() 7. button = tk.Button(text="Click me!") 8. button.pack() 9. tk.mainloop() 10. - Line 2; window = tk.Tk() - Line 2; window = Tk.Tk() - Line 10; window = Tk().tk - Line 10; window = tk.Tk()

Line 2; window = tk.Tk()

Tkinter provides a mainloop()method. It is used when your application is ready to run. mainloop() is an infinite loop used to run the application, wait for an event to occur and process the event as long as the window is not closed. What is missing in the code segment below? import tkinter as tk m = tk.Tk() ''' widgets are added here ''' - The last statement is missing. It should be m.mainloop() - The 2nd statement is missing. It should be m.mainloop() - The last statement is missing. It should be m.Mainloop() - The last statement is missing. It should be mainloop()

The last statement is missing. It should be m.mainloop()

Why do programmers use if statements? - To have Turtle make decisions based on conditional statements - To tell Turtle to do something if we run our code - To tell Turtle to stop our code if there's an error - To have Turtle complete one function at a time

To have Turtle make decisions based on conditional statements
