python线程池threadpool使用篇

pip installthreadpool

import threadpool 
def ThreadFun(arg1,arg2): 
 pass 
def main(): 
 device_list=[object1,object2,object3......,objectn]#需要处理的设备个数 
 task_pool=threadpool.ThreadPool(8)#8是线程池中线程的个数 
 request_list=[]#存放任务列表 
 #首先构造任务列表 
 for device in device_list: 
 request_list.append(threadpool.makeRequests(ThreadFun,[((device, ), {})])) 
 #将每个任务放到线程池中，等待线程池中线程各自读取任务，然后进行处理，使用了map函数，不了解的可以去了解一下。 
 map(task_pool.putRequest,request_list) 
 #等待所有任务处理完成，则返回，如果没有处理完，则一直阻塞 
 task_pool.poll()

 main()
