Topic: Classes and Objects

🔍 True or False

1. In Python, you create a class using the class keyword.
2. The `__init__` method is called automatically when a new object is created.
3. Instance attributes are shared across all objects of a class.
4. The `self` parameter is used to refer to the current instance of the class
5. Class attributes are defined inside the constructor using the `self` parameter.
6. Methods in a class operate on the object's data.

🧠 Example-Based True or False

1. class Car:
       def __init__(self, make, model):
           self.make = make
           self.model = model
   my_car = Car("Toyota", "Corolla")
   

   The `__init__` method is used to initialize the attributes of the `Car` class.

2. class Student:
       school = "High School"
   student1 = Student()
   student2 = Student()
   student1.school = "Middle School"
   

   Changing the `school` attribute of `student1` will also change it for `student2`.

3. class Dog:
       def bark(self):
           print("Woof!")
   my_dog = Dog()
   my_dog.bark()
   

   The `bark` method is an instance method of the `Dog` class.

4. class Circle:
       pi = 3.14
   print(Circle.pi)
   

   The `pi` attribute is a class attribute of the `Circle` class.
