Thanks, so does that mean we don't have to worry about errors in 3.8 and
just focus on 3.7.
in the case of typing/typing_extensions, 3.6 and 3.7 are the same and 3.8
behaves differently.
```
try:
# Literal, Protocol and TypedDict are only added to typing module
starting from
# python 3.8 we can safely remove this shim import after Airflow drops
# support for <3.8
from typing import Literal, Protocol, TypedDict, runtime_checkable #
type: ignore
except ImportError:
print("Import error")
from typing_extensions import Literal, Protocol, TypedDict,
runtime_checkable # type: ignore # noqa
```
