You can convert it to a list or tuple with list () or tuple (). 5. If maxsize is less than or equal to zero, the queue size is infinite. deque::empty() and deque::size() in They are optimized for fast fixed-length operations and incur O(n) memory movement costs for pop(0) and insert(0, v) operations which change both the size and position of the underlying data representation. collections — Container datatypes — Python 3,10,0 . A deque is a generalisation of both a stack and a queue. fix micropython/deque2.py at master · micropython/micropython python deque与列表的区别：根据index读list，时间复杂度为O(1)，deque是O(n)在两头插入数据，deque的时间复杂度为O(1), list为O(n)deque是一个双向链表，所以操作头尾非常简单。随机往中间插入数据，deque与list的时间复杂度都是O(n)deque 是 double-ended queue的缩写，类似于 list，不过提供了在两端插入和删除的操作。 Further... to append left and pop right: l = [] l.insert(0, x) # l.appendleft(x) l = l[-5:] # maxlen=5 . full(): It will return TRUE if the queue is full otherwise it will return FALSE. Further... to append left and pop right: l = [] l.insert(0, x) # l.appendleft(x) l = l[-5:] # maxlen=5 Would be your appendleft() equivalent should you want to front load your list without using deque. Queue, stack, and deque (double-ended queue) in Python A deque accepts a maxlen argument which sets the bounds for the deque. Hybrid Deque To represent a scatter plot, we will use the matplotlib library. Deque in Python - Tutorials Point Other great places for a tuple: the default argument for something that takes in a Sequence, since defaulting to an empty list can be dangerous.

The Deque module is a part of collections library. It has the methods for adding and removing elements which can be invoked directly with arguments. collections — Container datatypes — Python 3,10,0 . etl::ideque may be used as a size independent pointer or reference type for any etl::deque instance.
