ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
when using urlretrieve
"Open a terminal and take a look at:
/Applications/Python 3.6/Install Certificates.command
Python 3.6 on MacOS uses an embedded version of OpenSSL, which does not use the system certificate store. More details here.
(To be explicit: MacOS users can probably resolve by opening Finder and double clicking Install Certificates.command)"
