python线程池

import time
# threadpool为线程池模块
import threadpool


def 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
