python 是一知半解,属于急忙有车就上的认知,摸了一天才知道子进 /线程无法直接去操作主线程的队列,
改变想法,从进 /线程里面回调”推”任务出来,在进 /线程结束后,由主线程对列表任务进行操刀处理加入到队列,
才发现在回调函数里面似乎受限制了,如何破?

# 最终结果列表,全局的味道 GGlobalList = []  def procSome(xx):     return xxList  def multiProcFun():     BABTaskDict = {'TkNum': 32,                    'TkString': 'test String'}      def procFun(taskInfo):         aDataList = []         for i in range(1, 7)             taskNumber = taskInfo.get('TkNum')             taskString = taskInfo.get('TkString')             somethingList = procSome(taskNumber, taskString)             ...             ...             aDataList = aDataList + somethingList         if aDataList:             return aDataList         else:             return None      with concurrent.futures.ProcessPoolExecutor(max_workers=3) as executor:         def cb_fun(res):             data = res.result()             if data:                 # global GGlobalList # 很显然这里就算声明了要用，也是不行的                 # GGlobalList = GGlobalList + data   <--报:                 # UnboundLocalError: local variable 'addtomtQueenList' referenced before assignment                 # 错误          to_do = []         future = executor.submit(procFun, BABTaskDict).add_done_callback(cb_fun)         to_do.append(future)  if __name__ == '__main__':     ltQueen = queue.LifoQueue()     multiProcFun()      for i in GGlobalList:         ltQueen.put(i)              # 如果能在 procFun 里面直接操作 ltQueen 就好了...
