A deque (double-ended queue) allows efficient addition and removal of elements from both ends, unlike a list which is optimized for sequential access.
from collections import deque
dq = deque([1, 2, 3])
dq.appendleft(0) # Adds 0 to the beginning
dq.append(4) # Adds 4 to the end
print(dq) # Output: deque([0, 1, 2, 3, 4])
