Solution

The method that is called automatically when an object is initialized is the __init__ method. This method is known as a constructor in object-oriented concepts. Here's how it works:

  1. When you create an object of a class, Python calls this __init__ method to initialize the new object to initial states or values.

  2. This method is automatically called, you do not need to call it explicitly.

  3. The __init__ method can have any number of parameters, but the first parameter will always be a variable called self. This is a reference to the object that is being initialized.

  4. You can use this self parameter to access other attributes or methods of the class.

Here is an example:

class MyClass:
    def __init__(self):
        self.my_attribute = "Initial value"

# Create an object of MyClass
my_object = MyClass()

# Print the initial value of my_attribute
print(my_object.my_attribute)  # Output: Initial value

In this example, __init__ is called automatically when MyClass() is executed, and my_attribute is initialized to "Initial value".
