# flake8-pep604

flake8 plugin which forbids use of `typing.Union` (in favour of `|`), per [PEP

604](https://www.python.org/dev/peps/pep-0604/).

Note the `|` notation is a syntax error for Python \< 3.10. In this case you can

use the `annotations` feature (see [PEP 563](https://peps.python.org/pep-0563/)).

## flake8 Codes

| Code   | Description                                      |

|--------|--------------------------------------------------|

| UNT001 | Use `\|` in place of `typing.Union`. See PEP-604 |

## Motivation

Motivated by just wanting to make a codebase consistent in usage between

`typing.Union` and union types.

Note you could also automate this via

[`pyupgrade`](https://github.com/asottile/pyupgrade#pep-604-typing-rewrites)
