python名称错误：未定义全局名称

我收到此错误名称错误：未定义全局名称“控制队列” 我已经检查了整个控制队列，我认为我创建它是正确的

这是我的密码：

import multiprocessing 
import time 
from threading import Thread

class test_imports:#Test classes remove 
      alive = {'import_1': True, 'import_2': True};

      def halt_listener(self, control_Queue, thread_Name, kill_command):

              print ("isAlive", isAlive)
              if isAlive == kill_command:

                   return 
                else:

if __name__ == '__main__':
    # Establish communication queues
    control = multiprocessing.Queue()
    manager = worker_manager()

    runNum = int(raw_input("Enter a number: ")) 
    threadNum = int(raw_input("Enter number of threads: "))
    threadName = raw_input("Enter number: ")
    thread_Count = 0

    print ("Starting threads") 

    for i in range(threadNum):
        manager.generate(control, threadName, i)
        thread_Count = thread_Count + 1              

    time.sleep(runNum)#let threads do their thing

    print ("Terminating threads")     

    for i in range(thread_Count):
        control.put("t1kill")
        control.put("t2kill")

    manager.terminate(threadName) 

我想这是说我没有正确地创建它，但我看了一些队列教程，就我所知，它是正确的。有人能指出我把事情搞砸了吗？谢谢各位

在函数halt\u listener中，您的参数是control\u Queue，但您使用的是变量control\u Queue大写问题。

在函数halt\u listener中，您的参数是control\u Queue，但您使用的是变量control\u Queue大写问题。

在python中，control\u Queue与control\u Queue不同。案件敏感性问题。 您将参数设置为control\u Queue，但稍后将使用control\u Queue。

这种情况是错误的。isAlive=control\u queue.get应为 isAlive=control\u Queue.get

有几个地方发生了这种情况
