python - 如何访问类中的局部变量

Question

我正在处理一项任务，并试图访问一个类中的函数内的局部变量。有谁知道如何从类中的函数打印局部变量？我们不允许在类中的函数内打印任何内容，所以我想知道如何做到这一点。

def driver():
    q = my_queue.Queue_()
    for line in df:
        if 'received' in line:
            q.enqueue(line)
            print("Adding job " + q.new_item.job_ID + " to the queue with the timestamp: " + q.new_item.time_stamp + ".")
            print("The prority of the job is: " + q.new_item.job_priority)
            print("The job type is: " + q.new_item.job_type)
        if 'respond' in line:
            q.dequeue()
            print("Completed job " + q.current.job_ID + " in " + str(int(q.time_elapsed)) + " seconds.")
        if 'active' in line:
            q.active_jobs()
            print("Total number of jobs: " + str(len(q.active_jobs.temp)))
            print("Average priority: " + str(q.active_jobs.average))

我正在尝试打印最后两行，但这就是发生错误的地方。我得到的错误是：AttributeError：'function'对象没有属性'temp'。

这是类中的函数：

def active_jobs(self):
        if self.head == None:
            pass
#             print("No Jobs Available. ")
        else:
            current = self.head
            self.temp = []
            while current:
                self.temp.append(current.get_data())
                current = current.get_next()
            return self.temp
#             print("Total number of jobs: " + str(len(self.temp)))
            self.priority = []
            for i in range(len(self.temp)):
                self.priority.append(self.temp[i][2])
            x = [int(i) for i in self.priority]
            self.average = sum(x) / len(x)
            return self.average

active_jobs 创建temp实例属性。假设实例是q; 使用 访问该属性q.temp。
