python
import requests

# Disable SSL certificate verification (not recommended)
requests.packages.urllib3.disable_warnings()

# Define the URL to test
url = 'https://example.com'

try:
response = requests.get(url, verify=True)
# Process the response as needed
print(response.text)

except requests.exceptions.SSLError as e:
print(f"SSL Error: {str(e)}")
# Handle the SSL error here

except requests.exceptions.RequestException as e:
print(f"Request Exception: {str(e)}")
# Handle other request exceptions here

In the code snippet above, we import the `requests` library and disable SSL certificate verification using `requests.packages.urllib3.disable_warnings()` (not recommended for production use). This allows requests to proceed even if the SSL certificate has issues.

We then define the URL you want to test (`https://example.com` in this case), and make a `GET` request to that URL using `requests.get()`. If an `SSLError` occurs, the code will catch it and you can handle the error accordingly. Similarly, other request exceptions can be caught and handled separately.

Please note that this sample code is just a basic illustration and may not address the specific use case you have in mind. Additionally, disabling SSL certificate verification is generally not recommended for security reasons.
