Python是一種十分強大的編程語言，它在物聯網應用中也得到了廣泛的應用。Python提供了很多開源庫，可以用于各種物聯網應用程序中。下面我們就來介紹一些常用的Python物聯網庫。

1. MQTT庫

import paho.mqtt.client as mqtt
def on_connect(client, userdata, flags, rc):
print("Connected with result code {0}".format(str(rc)))
def on_message(client, userdata, msg):
print("{0} {1}".format(msg.topic, str(msg.payload)))
client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.connect("localhost", 1883, 60)
client.subscribe("test")
client.loop_forever()

2. CoAP庫

from coapthon.client.helperclient import HelperClient
client = HelperClient(server=('localhost', 5683))
response = client.post("other", "payload")
print(response.pretty_print())
client.stop()

3. Tornado庫

import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, World")
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()

總之，Python提供了很多強大的物聯網庫，可以用于開發各種應用程序，讓我們在物聯網領域發揮更大的作用。
