5.

6. root = tk.Tk()

7. label = tk.Label(root, text="Click me!")

8. label.bind("", change_color)

9. label.pack()

10.

11. root.mainloop()

What will happen when you click on the label?

Options :

A : The label-s background color will change to red.

B : The label will disappear from the window.

C : The label-s text will change to "Click me!"

D : The label-s font size will increase.

Answer: A

Question 2

What is the main reason for subclassing a built-in class?

Options :

A : It allows you to override all the parent-s methods.

B : It allows you to get a new class that can enrich parent-s methods.

C : It allows you to avoid any intellectual rights issues.

D : It allows you to make the code execution faster.

Answer: B

Question 3

You have the following snippet of code:

import abc

class Figure(abc.ABC):

@abc.abstractmethod

def area(self):

pass

class Square(Figure):

def __init__(self, a):

self.a = a

def area(self):

return self.a * self.a

Which of the following statement is true?

Options :

A : This code is erroneous. The @abc.abstractmethod decorator should be applied at the class level, not the method level.

B : You can create an instance of the Square class.

C : This code is erroneous. You should use the @abc.abstractclass decorator instead of @abc.abstractmethod.

D : You can create an instance of the Figure class.

Answer: B

Question 4

Which of the following best describes the concept of single inheritance in object-oriented programming (OOP)?

B : Single inheritance is the process of creating objects from a class and reusing its attributes and methods.

C : Single inheritance is the ability of a class to inherit properties and behaviors from its immediate parent class.

D : Single inheritance is the process of hiding certain attributes and methods of a class from its derived classes.

Answer: C

Question 5

The following code snippet attempts to call a method with multiple arguments in Python. Identify the correct syntax for calling the method and provide the correct code snippet.

class Calculator:

def add_numbers(self, num1, num2):

return num1 + num2

# Attempt to call the add_numbers method

calculator = Calculator()

Options :

A : result = Calculator.add_numbers(3, 4, 5)

B : result = add_numbers(3, 4, 5)

C : result = calculator.add_numbers([3, 4, 5])

D : result = calculator.add_numbers(3, 4, 5)
