### `Union` no Python 3.10 { #union-in-python-3-10 }

Neste exemplo, passamos `Union[PlaneItem, CarItem]` como o valor do argumento `response_model`.

Dado que estamos passando-o como um **valor para um argumento** em vez de colocá-lo em uma **anotação de tipo**, precisamos usar `Union` mesmo no Python 3.10.

Se estivesse em uma anotação de tipo, poderíamos ter usado a barra vertical, como:

* [kubelet] Auto-discover node IP if neither cloud provider exists and IP is not explicitly specified ([#29907](https://github.com/kubernetes/kubernetes/pull/29907), [@luxas](https://github.com/luxas))

and looked very uncomfortable.

  The moment Alice appeared, she was appealed to by all three to
settle the question, and they repeated their arguments to her,
though, as they all spoke at once, she found it very hard indeed
to make out exactly what they said.

  The executioner's argument was, that you couldn't cut off a
head unless there was a body to cut it off from:  that he had

  At this point it should be functionally mostly identical to the iptables
  mode, except that it does not (and will not) support Service NodePorts on
  127.0.0.1. (Also note that there are currently no command-line arguments
  for the nftables-specific config; you will need to use a config file if
  you want to set the equivalent of any of the `--iptables-xxx` options.)
