Topic #: 6
Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)
Option B is true because theunbind()method is invoked from within a widget's object1.
Option D is true because theunbind()method needs the event name as an argument1.
Theunbind()method in Tkinter is used to remove a binding between an event and a function. It can be invoked from within a widget's object when a binding is no longer needed. The method requires the event name as an argument to remove the binding for that specific event. For example:
button = tk.Button(root, text='Click me')
button.bind('<Button-1>', callback_function) # bind left mouse click event to callback_function
button.unbind('<Button-1>') # remove the binding for the left mouse click event
