• A method of structuring a program by bundling related properties and behaviors into individual objects.

How do you define a class in Python?

• Using the def keyword followed by the class name.

• Using the class keyword followed by the class name and a colon.

• By declaring it inside a function.

• By importing it from a module.

What are class attributes?

• External libraries included in a class.

• Attributes that have different values for each instance of a class.

• Functions defined inside a class.

• Attributes that have the same value for all instances of a class.

How do you instantiate a class in Python?

• By assigning it to a variable.

• By calling the class followed by parentheses.

• By using a special method called __init__().

• By calling the class using the class keyword.

What is inheritance in the context of Python classes?

• A module that inherits properties from another module.

• A function that inherits properties from another function.

• Copying the behavior of a class to another class.

• A process by which one class takes on the attributes and methods of another.

What is the purpose of the __init__() method?

• To define the final attributes of a class.

• To inherit methods from the parent class.

• To check if a class is initialized properly.

• To initialize the class's attributes with the self keyword.

What does the 'self' keyword represent in a class method's parameters?

• A reference to the current instance of the class.

• A static method that does not need an instance.

• A placeholder for future attributes.

• A keyword to make a method private.

How do you create a child class that inherits from a parent class?

• By using the inherit keyword.

• By declaring it outside the parent class.

• By putting the name of the parent class in parentheses after the child class name.

• By copying all attributes and methods from the parent class.

What is the correct way to call a method from a parent class using super()?

• super().methodName(args)

• super.methodName(args)

• parentClass.methodName(self, args)

• methodName(super, args)

Which statement is true about class attributes?

• They have the same value for every instance of the class.

• They must be initialized using the __init__() method.

• They are defined within methods.

• They are unique to each instance.
