python线程池

import time# threadpool为线程池模块import threadpooldef test(str):    print str    time.sleep(2)if __name__ == "__main__":    startTime = time.time()    # 创建线程池,最多创建的线程数为10    pool = threadpool.ThreadPool(10)    # 创建请求（类似于线程创建),test是目标函数，arts_list为目标函数的参数    requests = threadpool.makeRequests(test, args_list=['thread1', 'thread2', 'thread3', 'thread4'])    # 将请求放入线程池中启动    [pool.putRequest(req) for req in requests]    # 等待所有线程执行完毕    pool.wait()    endTime = time.time()    print endTime - startTime

单线程执行该方法的结果

def test(str):    print str    time.sleep(2)if __name__ == "__main__":    startTime = time.time()    for i in range(4):        test(str(i))    endTime = time.time()    print endTime - startTime
