This article shows how to create and manage container leases using the [Azure Storage client library for Python](/python/api/overview/azure/storage). You can use the client library to acquire, renew, release and break container leases.

1. Add code to run the program using `asyncio.run`. This function runs the passed coroutine, `main()`in our example, and manages the `asyncio` event loop. Coroutines are declared with the async/await syntax. In this example, the `main()` coroutine first creates the top level `BlobServiceClient` using `asyncwith`, then calls the method that acquires the container lease. Note that only the top level client needs to use `asyncwith`, as other clients created from it share the same connection pool.
1. Add code to acquire a container lease. The code is the same as the synchronous example, except that the method is declared with the `async` keyword and the `await` keyword is used when calling the `acquire` method.
