添付のコードに従って、クラス testのクラスBroadcastServerFactoryからブロードキャスト関数を呼び出すのを手伝ってくれませんか

別のクラスから関数を呼び出す非常に多くの方法を試しましたが、解決策はありません

class test():
  def __init__(self, factory):
    factory.broadcast("I don't know what I'm doing!")

そんな中、主に…

factory = ServerFactory("ws://localhost:9000",
  debug = debug,
  debugCodePaths = debug)

test(factory)

これはあなたが望むことをしますが、クラスとインスタンスに関するいくつかのコアコンセプトが欠けているようです. クラスが別のtestクラスで何かを呼び出すには、最初にそのインスタンスが必要です (静的メソッドの場合を除きます)。
