The following code samples, which use the Google APIs Client Library for Python, are available for the YouTube Live Streaming API. You can download these code samples from the python folder of the YouTube APIs code sample repository on GitHub.

1. Create a broadcast (liveBroadcasts.bind, liveBroadcasts.insert, liveStreams.insert)
2. Retrieve a channel's broadcasts (liveBroadcasts.list)
3. Retrieve a channel's live video streams (liveStreams.list)

Create a broadcast

The code sample below calls the API's liveBroadcasts.insert method to create a broadcast.
