[Bug 1936667] Re: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3

 

The following command would detect what we should replace...

egrep -r -e
'collections\.(Awaitable|Coroutine|AsyncIterable|AsyncIterator|AsyncGenerator|Hashable|Iterable|Iterator|Generator|Reversible|Sized|Container|Callable|Collection|Set|MutableSet|Mapping|MutableMapping|MappingView|KeysView|ItemsView|ValuesView|Sequence|MutableSequence|ByteString)'
--exclude-dir .tox --exclude-dir doc .
