This is a simple example showing how to use the [Paho MQTT Python client](https://eclipse.org/paho/clients/python/) to send data to Azure IoT Hub. You need to assemble the rights credentials and configure TLS and the MQTT protocol version appropriately.

send_iot-hub_paho_mqtt.py

#!/usr/bin/python

import paho.mqtt.publish as publish
import paho.mqtt.client as mqtt
import ssl

auth = {
  'username':"ciscohackhub.azure-devices.net/lora1",
  'password':"SharedAccessSignature sr=ciscohackhub.azure-devices.net%2Fdevices%2Flora1&sig=xxxx&se=1463048772"
}

tls = {
  'ca_certs':"/etc/ssl/certs/ca-certificates.crt",
  'tls_version':ssl.PROTOCOL_TLSv1
}

publish.single("devices/lora1/messages/events/",
  payload="hello world",
  hostname="ciscohackhub.azure-devices.net",
  client_id="lora1",
  auth=auth,
  tls=tls,
  port=8883,
  protocol=mqtt.MQTTv311)
