Another useful case is when you want to have keys of another type (e.g., `int`).

That's what we are going to see here.

In this case, you would accept any `dict` as long as it has `int` keys with `float` values:

=== "Python 3.9+"

    ```Python hl_lines="7"
    {!> ../../../docs_src/body_nested_models/tutorial009_py39.py!}
    ```

=== "Python 3.8+"

    }
    assertFailsWith<IllegalArgumentException> {
      key = (
        "this_is_way_too_long_this_is_way_too_long_this_is_way_too_long_" +
          "this_is_way_too_long_this_is_way_too_long_this_is_way_too_long"
      )
      cache.edit(key)
    }.also { expected ->
      assertThat(expected.message).isEqualTo("keys must match regex [a-z0-9_-]{1,120}: \"$key\"")
    }

  // and notAfter fields in the issued certificate to determine the actual duration.
  //
  // The v1.22+ in-tree implementations of the well-known Kubernetes signers will
  // honor this field as long as the requested duration is not greater than the
  // maximum duration they will honor per the --cluster-signing-duration CLI
  // flag to the Kubernetes controller manager.

Or you might have any other way to communicate with the WebSocket endpoint.

But for this example, we'll use a very simple HTML document with some JavaScript, all inside a long string.

This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.
