What is the extend method in Python's deque?

Can you explain the extend method in Python's deque?

Sure! The extend method in Python's deque allows you to add multiple elements to the right end of the deque.

How does it differ from the append method?

The append method adds a single element to the right end, while extend can add an iterable of elements.

Can you show me a code example?

Of course! Here's a simple example:

from collections import deque

my_deque = deque([1, 2, 3])
my_deque.extend([4, 5, 6])
print(my_deque)  # Output: deque([1, 2, 3, 4, 5, 6])

What happens if I use extend with a string?

If you use extend with a string, it will add each character of the string as a separate element in the deque.
