How to slice a deque in python?

In Python, you can slice a deque using the same slicing syntax as you would for a regular list or other sequence types. A deque is a double-ended queue, which means you can slice it from both ends. Here's how you can slice a deque:

from collections import deque # Create a deque my_deque = deque([1, 2, 3, 4, 5]) # Slice the deque from index 1 to 3 (exclusive) sliced_deque = my_deque[1:3] print(sliced_deque) # Output: deque([2, 3])

In this example, we create a deque named my_deque containing five elements. We then use slicing to extract a portion of the deque from index 1 (inclusive) to index 3 (exclusive), resulting in a new deque named sliced_deque.

You can also slice the deque in reverse order by specifying a negative step:

# Slice the deque in reverse order from index -3 to -1 (exclusive) reverse_sliced_deque = my_deque[-3:-1] print(reverse_sliced_deque) # Output: deque([3, 4])

In this example, we slice the deque in reverse order, starting from the third-to-last element and ending at the last element.

You can use slicing to extract a subsequence of elements from a deque or create a new deque containing those elements.
