Complete the add_document() function to add a document to the queue. Complete the print_documents() function to iterate

Here's the code to complete the `add_document()` function to add a document to the queue and the `print_documents()` function to iterate over the queue while it has elements, and remove each document in the queue: ``` class PrinterTasks: def __init__(self): self.queue = Queue() def add_document(self, document): # Add the document to the queue self.queue.put(document) def print_documents(self): # Iterate over the queue while it has elements while not self.queue.empty(): # Remove the document from the queue print("Printing", self.queue.get()) ``` This creates a class called `PrinterTasks` with a constructor that initializes a `Queue` object called `queue`. The `add_document()` method adds a document to the queue using the `put()` method. The `print_documents()` method iterates over the queue using the `empty()` method to check if the queue is empty, and removes each document from the queue using the `get()` method and prints it.
