Quiz: Quiz 5: Classes and Objects Fundamentals

1. What is the primary purpose of the `__init__` method in a Python class?

To destroy an object.

To initialize a new object's attributes.

To define class-level variables.

To be called explicitly by the user after object creation.

2. In a class method definition, what does the `self` parameter refer to?

The class itself.

A global variable.

The specific instance of the class on which the method is called.

The parent class.

3. How do you create an object (an instance) of a class named `MyClass`?

`MyClass.create()`

`new MyClass()`

`MyClass()`

`object MyClass = new`

4. If `my_object` is an instance of a class that has a method `do_something()`, how do you call this method?

`call my_object.do_something()`

`my_object.do_something()`

`do_something(my_object)`

`MyClass.do_something(my_object)`

5. What is a class in Object-Oriented Programming?

A specific, concrete entity with data and behavior.

A blueprint or template for creating objects.

A function that performs an action.

A built-in Python data type like list or dict.

6. What is a primary goal of Object-Oriented Programming (OOP)?

To write code that is as short as possible.

To make all data globally accessible.

To model real-world entities and their interactions by organizing code into objects and classes, promoting reusability and modularity.

To execute code faster than procedural programming.

7. Can a Python class have multiple methods?

No, only one method per class.

Yes, a class can define multiple methods.

Only if it's a very complex class.

Yes, but they must all have different names for `self`.

8. If `car1` is an object of a `Car` class and `brand` is an attribute, how do you access its value?

`car1.getBrand()`

`car1[brand]`

`car1.brand`

`Car.brand(car1)`
