Suppose you are writing a program for an item catalog. Model a
class for that purpose.
Here is an example of a class that could be used to model an item for an item catalog program:

```python
class CatalogItem:
    def __init__(self, item_id, name, description, price):
        self.item_id = item_id
        self.name = name
        self.description = description
        self.price = price

    def get_item_id(self):
        return self.item_id

    def get_name(self):
        return self.name

    def get_description(self):
        return self.description

    def get_price(self):
        return self.price

    def set_name(self, new_name):
        self.name = new_name

    def set_description(self, new_description):
        self.description = new_description

    def set_price(self, new_price):
        self.price = new_price

```

This `CatalogItem` class contains information about an item in the catalog, including its unique item ID, name, description, and price. The class also includes methods for getting and setting these attributes, making it easy to access and update information about each item in the catalog.
Below is an instruction that describes a task, write a response that appropriately completes the request.

        self.price = price

    def get_item_id(self):
        return self.item_id

    def get_name(self):
        return self.name

    def get_description(self):
        return self.description
