Updating an existing role is very similar. The update_role() function call accepts the role ID and the role parameters, which are used to update the existing role represented by the role ID:

def update_role(conn):
    role_id = "ce5156690f4c48bda5b5b9041325e493"
    role_desc = {
                "description":"This is a test role",
                "isenabled" : False,
                "name":"packtpub"
    }
    conn.identity.update_role(role_id, **role_desc)
