Window¶
Running window data structure.
This is just a convenience layer on top of a collections.deque. The only reason this exists is that deepcopying a class which inherits from collections.deque seems to bug out when the class has a parameter with no default value.
Parameters¶
-
size (int)
Size of the rolling window.
Attributes¶
- size
Examples¶
>>> from river import utils
>>> window = utils.Window(size=2)
>>> for x in [1, 2, 3, 4, 5, 6]:
... print(window.append(x))
[1]
[1, 2]
[2, 3]
[3, 4]
[4, 5]
[5, 6]
