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()
以上这篇python自定义线程池控制线程数量的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
