collections导入错误

从Python3中导入collections

from collections import Iterable
from collections import Iterator

出现以下错误

DeprecationWarning: Using or importing the ABCs from ‘collections’ instead of from ‘collections.abc’ is deprecated since Python 3.3, and in 3.9 it will stop working from collections import Iterator

解决方法为修改导入collections的方式

from collections.abc import Iterable
from collections.abc import Iterator
