Human: Can you show me a Python function to add items to iterable objects. Assistant: 
Here is a Python function to add items to iterable objects

import itertools

def add_to_iterable(iterable, item):
    """
    >>> iterable = [1, 2, 3]
    >>> add_to_iterable(iterable, 4)
    >>> iterable
    [1, 2, 3, 4]
    """
    iterable.append(item)

# Enter the iterable
iterable = [1, 2, 3]

# Enter the item
item = 4

# Calling the function
print((add_to_iterable(iterable, item)))

#Example Output
# None

#Remember to inspect code for bugs.
