How to Suppress the SSL Warning in Python/pyVmomi

I was experimenting with the VMware Web service SDK using pyVmomi and I got some error that need to be documented her. I’m using pyVmomi 6.0.0 in a vSphere 6 environment.
The first one was an SSL warning when using pyVmomi to acquire a service instance, if you try to use SmartConnect you will get the following ssl error:

I/O error(1): [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)

I forgot that I needed to secify an SSL context, this context describe the various SSL options. Her is how to use it:

import ssl
....
# your other stuff
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_NONE

# Getting the Sevice Instance
    try:
        si = connect.SmartConnect(protocol="https",host=args.vc,port=443,user=args.user,pwd=args.pwd,sslContext=context)
    except IOError as e:
        print ("Could not connect to the vCenter instance error({}): {}".format(e.errno, e.strerror))
....

How about the requests module in Python ?

If you are also trying to use this module with an untrusted SSL certificate, you will get the following error:

disable C:\Python35\lib\site-packages\requests\packages\urllib3\connectionpool.py:821: InsecureRequestWarning: Unverified HTTPS request is
being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html InsecureRequestWarning)

You have two choice her:

1- Disable All urllib3 warning like this

import urllib3
urllib3.disable_warnings()
...

Or

2 -Disable only this specific kind of error => InsecureRequestWarning:

from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
....
