What are the different methods of a deque in Python?

In Python, a deque (double-ended queue) has several methods like append(), appendleft(), pop(), popleft(), and more. Would you like details on any specific method?

Can you explain the append() and appendleft() methods?

Sure! The append() method adds an element to the right end of the deque, while appendleft() adds an element to the left end. This allows for efficient insertion at both ends.

What about pop() and popleft()?

The pop() method removes and returns an element from the right end, while popleft() removes and returns an element from the left end. They are useful for removing elements in a FIFO manner.

Are there any other useful methods?

Yes, there are methods like extend(), extendleft(), rotate(), and clear(). Each serves different purposes for managing the deque.
