### Lifespan function { #lifespan-function }

The first thing to notice, is that we are defining an async function with `yield`. This is very similar to Dependencies with `yield`.

{* ../../docs_src/events/tutorial003_py39.py hl[14:19] *}

The first part of the function, before the `yield`, will be executed **before** the application starts.

users in addition to our existing JAR for JVM users.

This first Android-specific artifact adopts Android's `assets` mechanism to embed the public suffix
data. We will build more Android integration in future releases.

The okhttp-android artifact first introduced in `5.0.0-alpha.7` is no longer available:

 *  The `AndroidAsyncDns` class moved to the `okhttp` artifact.

When you need to receive form fields instead of JSON, you can use `Form`.

/// info

To use forms, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
