deque()

In Python, a deque is a double-ended queue that allows fast appends and pops from both ends. The deque() method, a part of the collections module, creates a new deque object.

Syntax

my_deque = deque(iterable, maxlen)

• my_deque: The name of the deque object to be created.
• iterable: The iterable to be used for intializing the deque.
• maxlen: The maximum length for the deque.

Example

The following example demonstrates the usage of the deque method:

from collections import deque

fruit = 'apple'

fruit_slices = deque(fruit)

print(fruit_slices)

The above code produces the following output:

deque(['a', 'p', 'p', 'l', 'e'])

Here is another example using the deque method:

from collections import deque

friends = ['Dave', 'Mary', 'Luis', 'Zachary']

car_five_seater = deque(friends, 5)

print(car_five_seater)

The above code gives the following output:

deque(['Dave', 'Mary', 'Luis', 'Zachary'], maxlen=5)
