代码应该返回触发器对象 - 触发器映射的长度应该显示实际存在的触发器的实际数量......如果至少有一个或多个触发器，它应该返回 True 但它们都返回 FALSE 和零触发器...有人可以帮忙吗？代码在下面，测试人员的错误消息将打印在下面。

def makeTrigger(triggerMap, triggerType, params, name):

    def readTriggerConfig(filename):
        triggerfile = open(filename, "r")
        all = [ line.rstrip() for line in triggerfile.readlines() ]
        lines = []
        for line in all:
            if len(line) == 0 or line[0] == '#':
                continue
            lines.append(line)
            if len(line) >= 1:
                return True
        triggers = []
        triggerMap = {}

    # Be sure you understand this code - we've written it for you,
    # but it's code you should be able to write yourself
        for line in lines:

            linesplit = line.split(" ")

        # Making a new trigger
            if linesplit[0] != "ADD":
                trigger = makeTrigger(triggerMap, linesplit[1],
                                      linesplit[2:], linesplit[0])

        # Add the triggers to the list
            else:
                for name in linesplit[1:]:
                    triggers.append(triggerMap[name])

        return triggers

现在这里是来自测试人员的错误信息——如果可能的话请帮忙……我的脑子都糊涂了！！！总共有七个测试给出了这些错误消息，我仍然不知道如何修复它们！如果可以的话，请帮忙... ciao！

看起来您从未在 makeTrigger 函数中执行任何代码；您只是在定义另一个函数 readTriggerConfig。

您是否尝试过将 makeTrigger 函数与其余代码隔离开来，并使用一小组已知输入来运行它以更好地了解其行为？使用调试器逐步执行它可能会帮助您了解正在发生的事情。
