4.0.6 fails to import in Python <3.10

[UGlaeser-NI]

The most recent version (4.0.6) triggered by commit aa9998d fails to import in Python 3.9.13:

Python 3.9.13 (tags/v3.9.13:6de2ca5, May 17 2022, 16:36:42) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import ping3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\VirtEnvs\ping3\lib\site-packages\ping3\__init__.py", line 180, in <module>
    def receive_one_ping(sock: socket.socket, icmp_id: int, seq: int, timeout: int) -> float | None:
TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'
>>>

None (as opposed to NoneType) isn't allowed until Python 3.10 -> that's what's up. See https://stackoverflow.com/a/76712732

Potential solutions -> use https://pypi.org/project/future-typing/ and specify that # -*- coding: future_typing -*- at the top of files before using | typing. Alternatively, use typing.Union instead.

Obvious workaround, as this was introduced by 4.0.6, forcing 4.0.5 will be enough to get through that.

[mshafer-NI]

That is true, and that is what we are doing for now. We thought this was worth posting/bringing up since this is a breaking change in a patch update

Sorry for the inconvenience. The unsupported type hints are removed in version 4.0.7. Can you test if it works?

[mshafer-NI]

Can confirm, doing pip install -U ping3 in the venv this failed in yesterday upgrades to 4.0.7 and am then able to import ping3 successfully.

(Also, thank you for the quick fix)
