Error:

Fix error mac rllib.error.URLError SSL CERTIFICATE_VERIFY_FAILED certificate verify failed unable to get local issuer certificate

Solution:

This error occurs when Python is unable to verify the SSL certificate of a website you are trying to access. One solution for macOS users is to navigate to Applications/Python 3.x (where x is your version of Python) and double-click on Install Certificates.command 12. This should install the necessary certificates for Python to verify SSL connections.
