How to Disable SSL Certificate Checks in Python Requests?

Disabling Security Certificate Checks in Python Requests

To prevent SSL errors when accessing websites with expired certificates while using Python's requests library, the verify flag can be set to False. By default, requests verifies the server's SSL certificate to ensure a secure connection, but this verification can be bypassed.

To disable certificate verification, simply pass verify=False as an argument to the post method:

<code class="python">import requests
requests.post(url='https://foo.example', data={'bar':'baz'}, verify=False)</code>

Using a Context Manager for Persistent Disablement

If you need to disable certificate verification permanently for all requests, you can use a context manager:

<code class="python">import requests
from urllib3.exceptions import InsecureRequestWarning
import contextlib

@contextlib.contextmanager
def no_ssl_verification():
    warnings.simplefilter('ignore', InsecureRequestWarning)
    old_settings = requests.Session.merge_environment_settings
    requests.Session.merge_environment_settings = lambda *args, **kwargs: (dict(args[5] or {}), False)
    try:
        yield
    finally:
        requests.Session.merge_environment_settings = old_settings

with no_ssl_verification():
    requests.get('https://wrong.host.badssl.example/')</code>

Considerations

Keep in mind that disabling certificate verification weakens the security of your application. It is recommended to only do so when accessing websites you trust or in controlled environments where security is not a primary concern.
