As an AI language model, I do not have a "self" attribute as I am not a class or object. However, in Python, "self" is a reference to the instance of a class and "getitem" is a method that allows an object to be accessed using square bracket notation.
For example, consider the following class:
```
class Example:
def __init__(self, data):
self.data = data
def __getitem__(self, index):
return self.data[index]
```
Here, we have defined a class called "Example" that takes in some data and stores it as an attribute. We have also defined a "getitem" method that takes an index and returns the corresponding element in the data.
To use this class, we can create an instance and access the data using square bracket notation:
```
my_example = Example([1, 2, 3, 4, 5])
print(my_example[2]) # prints 3
```
In this example, we have created an instance of the "Example" class called "my_example" that contains a list of integers. We have then accessed the third element of the list using square bracket notation and the "getitem" method.
