Have you ever found yourself dealing with a long list in Python, and needing to quickly add or remove items from it? If so, you may want to consider using the deque() method from the collections module. This handy tool allows you to efficiently add and remove items from the beginning or end of a list, making it a valuable addition to your Python toolkit.
from collections import deque
# Create a deque with initial items
my_deque = deque(["apple", "banana", "cherry"])
# Add items to the end of the deque
my_deque.append("orange")
my_deque.appendleft("pear")
# Remove items from the end of the deque
my_deque.pop()
my_deque.popleft()
The code snippet above shows how to use the deque() method to create a list-like object and add or remove items from it. By using the append() and appendleft() methods, you can add items to the end or beginning of the deque, respectively. Similarly, the pop() and popleft() methods can be used to remove items from the end or beginning of the deque. Because deque is optimized for these operations, it can be faster and more efficient than using a regular Python list for this purpose.
