Official Hetzner Cloud python library.

The library's documentation is available at [hcloud-python.readthedocs.io](https://hcloud-python.readthedocs.io/en/stable/), the public API documentation is available at [docs.hetzner.cloud](https://docs.hetzner.cloud).

> [!IMPORTANT]
> Make sure to follow our API changelog available at
> [docs.hetzner.cloud/changelog](https://docs.hetzner.cloud/changelog) (or the RSS feed
> available at
> [docs.hetzner.cloud/changelog/feed.rss](https://docs.hetzner.cloud/changelog/feed.rss))
> to be notified about additions, deprecations and removals.

## Usage

Install the `hcloud` library:

```sh
pip install hcloud
```

For more installation details, please see the [installation docs](https://hcloud-python.readthedocs.io/en/stable/installation.html).

Here is an example that creates a server and list them:

```python
from hcloud import Client
from hcloud.images import Image
from hcloud.server_types import ServerType

client = Client(
    token="{YOUR_API_TOKEN}", # Please paste your API token here
    application_name="my-app",
    application_version="v1.0.0",
)

# Create a server named my-server
response = client.servers.create(
    name="my-server",
    server_type=ServerType(name="cx23"),
    image=Image(name="ubuntu-22.04"),
)
server = response.server
print(f"{server.id=} {server.name=} {server.status=}")
print(f"root password: {response.root_password}")

# List your servers
servers = client.servers.get_all()
for server in servers:
    print(f"{server.id=} {server.name=} {server.status=}")
```

- To upgrade the package, please read the [instructions available in the documentation](https://hcloud-python.readthedocs.io/en/stable/upgrading.html).
- For more details on the API, please see the [API reference](https://hcloud-python.readthedocs.io/en/stable/api.html).
- You can find some more examples under the [`examples/`](https://github.com/hetznercloud/hcloud-python/tree/main/examples) directory.

## Supported Python versions

We support python versions until [`end-of-life`](https://devguide.python.org/versions/#status-of-python-versions).

## Experimental features

Experimental features are published as part of our regular releases (e.g. a product
public beta). During an experimental phase, breaking changes on those features may occur
within minor releases.

The stability of experimental features is not related to the stability of its upstream API.

Experimental features have different levels of maturity (e.g. experimental, alpha, beta)
based on the maturity of the upstream API.

While experimental features will be announced in the release notes, you can also find
whether a python class or function is experimental in its docstring:

```
Experimental:
    $PRODUCT is $MATURITY, breaking changes may occur within minor releases.
    See https://docs.hetzner.cloud/changelog#$SLUG for more details.
```

## Development

First, create a virtual environment and activate it:

```sh
make venv
source venv/bin/activate
```

You may setup [`pre-commit`](https://pre-commit.com/) to run before you commit changes, this removes the need to run it manually afterwards:

```sh
pre-commit install
```

You can then run different tasks defined in the `Makefile`, below are the most important ones:

Build the documentation and open it in your browser:

```sh
make docs
```

Lint the code:

```sh
make lint
```

Run tests using the current `python3` version:

```sh
make test
```

You may also run the tests for multiple `python3` versions using `tox`:

```sh
tox .
```

### Deprecations implementation

When deprecating a module or a function, you must:

- Update the docstring with a `deprecated` notice:

```py
"""Get image by name

.. deprecated:: 1.19
    Use :func:`hcloud.images.client.ImagesClient.get_by_name_and_architecture` instead.
"""
```

- Raise a warning when the deprecated module or function is being used:

```py
warnings.warn(
    "The 'hcloud.images.client.ImagesClient.get_by_name' method is deprecated, please use the "
    "'hcloud.images.client.ImagesClient.get_by_name_and_architecture' method instead.",
    DeprecationWarning,
    stacklevel=2,
)
```

### Releasing experimental features

To publish experimental features as part of regular releases:

- an announcement, including a link to a changelog entry, must be added to the release notes.
- an `Experimental` notice, including a link to a changelog entry, must be added to the python classes and functions that are experimental:

  ```py
  """
  Experimental:
      $PRODUCT is $MATURITY, breaking changes may occur within minor releases.
      See https://docs.hetzner.cloud/changelog#$SLUG for more details.
  """
  ```
