How to update and set or unset a QOS Policy by python module

Hello, By using the following commands I can set/unset a port: openstack port set --qos-policy qos_policy_name "network_id" openstack port unset --qos-policy "network_id" But the issue is I cannot find the proper way to set/unset a port. I see this document: https://docs.openstack.org/openstacksdk/latest/user/proxies/network.html And I see the module has this method: *conn.network.update_port* But I don't see any more documents to see how to do that and what parameters are required. Can you help me?
