In [2]: mydeque = deque(maxlen=10)
In [3]: mydeque.maxlen
In [4]: mydeque.append(1)
In [5]: mydeque.append(10)
In [6]: mydeque
Out[6]: deque([1, 10])
In [7]: mydeque.appendleft(‘a‘)
In [8]: mydeque.appendleft(‘b‘)
In [9]: mydeque
Out[9]: deque([‘b‘, ‘a‘, 1, 10])
In [10]: mydeque.pop()
Out[10]: 10
In [11]: mydeque
Out[11]: deque([‘b‘, ‘a‘, 1])
In [12]: mydeque.popleft()
Out[12]: ‘b‘
In [13]: mydeque
Out[13]: deque([‘a‘, 1])
