python线程池怎么设置
python自定义线程池控制线程数量的示例1.自定义线程池
|
import threading import Queue import time queue = Queue.Queue() def put_data_in_queue(): for i in xrange ( 10 ): queue.put(i) class MyThread(threading.Thread): def run( self ): while not queue.empty(): sleep_times = queue.get() time.sleep(sleep_times) queue.task_done() def main_function(): threads_num = 6 while True : put_data_in_queue() for i in xrange (threads_num): myThread = MyThread() myThread.setDaemon( True ) myThread.start() queue.join() time.sleep( 60 ) |
2.多线程与signal信号的监控结合
|
import threading import Queue import time import signal queue = Queue.Queue() stop = False def receive_signal(signum, stack): signal.signal(signal.SIGTERM, original_sigterm) global stop stop = True def put_data_in_queue(): for i in xrange ( 10 ): queue.put(i) class MyThread(threading.Thread): def run( self ): while not queue.empty(): sleep_times = queue.get() time.sleep(sleep_times) queue.task_done() def main_function(): threads_num = 6 while not stop: put_data_in_queue() for i in xrange (threads_num): myThread = MyThread() myThread.setDaemon( True ) myThread.start() queue.join() time.sleep( 60 ) if __name__ = = "__main__" : original_sigterm = signal.getsignal(signal.SIGTERM) signal.signal(signal.SIGTERM, receive_signal) main_function() |
