Python 扭曲，reactor.callLater() 不推迟
Python twisted, reactor.callLater() not defering
以下代码片段来自 python 扑克牌服务器。该程序有效，除非在使用 reactor.callLater 时试图延迟锦标赛的开始。
变量 "wait" 从设置为“60”的 xml 文件中获取其整数。然而，延迟从未实施，比赛总是立即开始。我对 python 不是很熟悉，或者只是试图破解它为我工作而扭曲。然而，从我的角度来看，有一件事似乎它不应该工作，因为我看不到变量 "old_state" 如何或在何处获取其值以便代码正确确定服务器的状态。但也许我错了。
希望熟悉python和twisted的人能看出问题所在，并愿意就这个问题开导我。

我发现这段代码有几个导入的文件，它们位于我没有检查的另一个目录中。我还错误地假设了这个代码块的目的。我希望该功能是任意的，并将每次锦标赛延迟 n 秒，但实际上它仅在玩家忘记游戏并且没有出现时才实施延迟。一旦我检查了正确的文件，这些事实就很清楚了。学过的知识。看看所有的进口！
