In Python, which data structure can be used to implement a queue?
Step 1: Understand what a queue is. A queue is a data structure that follows the First In First Out (FIFO) principle.
Step 2: Know that in Python, you can use a list to create a queue. You can add items to the end of the list and remove items from the front.
Step 3: Realize that while lists can be used for queues, they are not the most efficient option because removing an item from the front of a list can be slow.
Step 4: Learn about collections.deque, which is a special type of list designed for fast appends and pops from both ends. It is more efficient for implementing a queue.
Step 5: Choose collections.deque for better performance when implementing a queue in Python.
