# xarray.show_backends

### xarray.show_backends(file=None, markdown=False)[[source]](https://github.com/pydata/xarray/blob/main/xarray/backends/plugins.py#L153-L214)

Print the available backends (engines) and information about them.

The backends are listed in the order in which they are tried when opening
a file without specifying the `engine`.
Use [`xarray.backends.list_engines()`](xarray.backends.list_engines.html.md#xarray.backends.list_engines) to get the backend objects.
In Jupyter notebooks the backends are displayed formatted.

* **Parameters:**
  * **file** ([file-like](https://docs.python.org/3/glossary.html#term-file-like-object), *optional*) – print to the given file-like object. Defaults to sys.stdout.
  * **markdown** ([`bool`](https://docs.python.org/3/builtins/functions.html#bool), *default*: [`False`](https://docs.python.org/3/builtins/constants.html#False)) – print a markdown list wrapped in a `<details>` block, which can be
    pasted as is into a GitHub issue.
