collections.deque is for this an optimized datatype.
It has
You can also initialize the deque with
Example with moving average:
It has
appendleft, popleft, pop, extendleft and rotate.You can also initialize the deque with
maxlen, which is the maximum size.Example with moving average:
import collections
def moving_average(iterable, size):
q = collections.deque(maxlen=size)
for element in iterable:
q.append(element)
yield sum(q) / len(q)
r20 = range(20)
list(moving_average(r20, 5))
