[Python] Problems using paho mqtt client with python 3.7

I am running the following code to connect to a mqtt server.

import paho.mqtt.client as mqtt
import ssl
import uuid

client = mqtt.Client(str(uuid.uuid1()))
client.tls_set(
"ca.crt",
"client.crt",
"client.key",
cert_reqs=ssl.CERT_REQUIRED,
tls_version=ssl.PROTOCOL_TLSv1
)
client.connect(
"127.0.0.1",
8883,
)
client.loop_forever()


This code works fine with python2.7 version. But when I run it with python3.7 version I am getting the below error.

Traceback (most recent call last):
File "test.py", line 29, in <module>
8883,
File "virtualenvs/mqtt-xG2h6zri/lib/python3.7/site-packages/paho/mqtt/client.py", line 839, in connect
return self.reconnect()
File "mqtt-xG2h6zri/lib/python3.7/site-packages/paho/mqtt/client.py", line 994, in reconnect

self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: IP address mismatch, certificate is not valid for '127.0.0.1'. (_ssl.c:1045)


Please help me figure out how to make this work in python 3.7.
