python自定义线程池控制线程数量的示例
作者：AdgerZhou
今天小编就为大家分享一篇python自定义线程池控制线程数量的示例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
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()
