Question
Which method is called automatically when an object is initialized?
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:
-
When you create an object of a class, Python calls this
__init__method to initialize the new object to initial states or values. -
This method is automatically called, you do not need to call it explicitly.
-
The
__init__method can have any number of parameters, but the first parameter will always be a variable calledself. This is a reference to the object that is being initialized. -
You can use this
selfparameter 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".
