python实现线程池

参照c++的线程池，使用python的threading库实现线程池。

import threading
import time


# 线程池的任务，包含一个可调用对象和一个参数数组
class ThreadTask(object):
    def __init__(self, job, args=list()):
        self.task = job
        self.args = args


# 线程池对象
class ThreadPool(object):
    # 初始化线程池的线程、任务队列、任务队列读写锁、睡眠唤醒线程的condition对象，并开启所有线程
    def __init__(self, thread_length):
        self.task_list = list()
        self.task_lock = threading.RLock()
        self.task_condition = threading.Condition()
        self.thread_length = thread_length
        self.thread_list = list()
        for i in range(0 , thread_length):
            self.thread_list.append(threading.Thread(name='Thread '+str(i), target=ThreadPool.thread_work,
                                                     args=[self]))
        for<
