我以前从未见过这个错误：

TypeError: unbound method halt_listener() must be called with test_imports instance as first argument (got Queue instance instead)

当我运行这段代码时，我明白了：

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

      def halt_listener(self, control_Queue, thread_Name, kill_command):
          while True:
              print ("Checking queue for kill")
              isAlive = control_queue.get()
              print ("isAlive", isAlive)
              if isAlive == kill_command:
                 print ("kill listener triggered")
                 self.alive[thread_Name] = False;
                 return

      def import_1(self, control_Queue, thread_Number):
          print ("Import_1 number %d started") % thread_Number
          t = Thread(target=test_imports.halt_listener, args=(control_Queue, 'import_1', 't1kill'))
          count = 0 
          t.run()
          global alive 
          run = test_imports.alive['import_1'];
          while run:
                print ("Thread type 1 number %d run count %d") % (thread_Number, count)
                count = count + 1
                print ("Test Import_1 ", run)
                run = self.alive['import_1'];
          print ("Killing thread type 1 number %d") % thread_Number

我认为def halt_listener(self, control_Queue, thread_Name, kill_command):尤其是这条线，self但我不确定是否有人对我应该如何处理这个问题有任何指导？谢谢！

您必须首先创建该类的实例：

def import_1(self, control_Queue, thread_Number):
    print ("Import_1 number %d started") % thread_Number
    myinstance = test_imports()
    t = Thread(target=myinstance.halt_listener, args=(control_Queue, 'import_1', 't1kill'))
