模塊導入from collections import Iterator,Iterable失敗

1.引入模塊報錯

　　from collections import Iterator,Iterable

報錯：
　　DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working from collections import Iterator,Iterable

2.修改為：

　　from collections.abc import Iterator,Iterable
