Die gute Nachricht ist, dass Sie sich darüber keine Sorgen mehr machen müssen, wenn Sie Python 3.10 verwenden, da Sie einfach `|` verwenden können, um Vereinigungen von Typen zu definieren:

{* ../../docs_src/python_types/tutorial009c_py310.py hl[1,4] *}

Und dann müssen Sie sich nicht mehr um Namen wie `Optional` und `Union` kümmern. 😎

#### Generische Typen

	var (
		prevPeerInfo, pi madmin.PeerInfo
	)
	if peer.DeploymentID != "" {
		pi = c.state.Peers[peer.DeploymentID]
		prevPeerInfo = pi
		if !peer.SyncState.Empty() { // update replication to peer to be sync/async
			pi.SyncState = peer.SyncState
			successMsg = fmt.Sprintf("%s\n- sync state %s for peer %s", successMsg, peer.SyncState, peer.Name)
		}
