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

The true statement about the__name__attribute isD.nameis a special attribute, which is inherent for classes, and it contains the name of a class. The__name__attribute is a special attribute of classes that contains the name of the class as a string.

The__name__attribute is a special attribute in Python that is available for all classes, and it contains the name of the class as a string. The__name__attribute can be accessed from both the class and its instances using the dot notation.

Deserialization is the process of converting data that has been serialized

For example, if you have a Python objectmy_objand you want to serialize it to a JSON string, you might do something like this:

import json

serialized_obj = json.dumps(my_obj)

To deserialize the JSON string back into a Python object, you would use thejson.loads()method:

deserialized_obj = json.loads(serialized_obj)

This would convert the JSON string back into its original Python object form.

Deserialization is the process of converting a sequence of bytes, such as a file or a network message, into a Python object. This is the opposite of serialization, which is the process of converting a Python object into a sequence of bytes for storage or transmission.

The unbind_all() method in Tkinter is used to remove all event bindings from a widget. It is a method of the widget object and can be called on any widget in the Tkinter application. Therefore, option A is the correct answer.

Option B is incorrect because the method can be called on any widget, not just the main window widget.

Option C is correct as unbind_all() does not take any parameters.

Option D is incorrect because the method only removes event bindings and does not cause the widgets to disappear.

So, the correct answers are A and C.

In the JSON processing context, the term serialization: A. names a process in which Python data is turned into a JSON string.

Serialization refers to the process of converting a data object, such as a Python object, into a format that can be easily transferred over a network or stored in a file. In the case of JSON, serialization refers to converting Python data into a string representation using the JSON format. This string can be sent over a network or stored as a file, and later deserialized back into the original Python data object.
