How to update version in the __init__.py when releasing next to updating pyproject.toml?

Currently i am releasing a python project with a pyproject.toml.

```
[tool.poetry]
version = "0.0.1"
```

Is it possible to also reflect that release number in the __init__.py so people can check what version they are using?

I tried to put a placeholder in the format:

```
file: __init__.py inside my package
__version__ = "0.0.0"
```
