pythonのurllibで ExceptionName=URLError, REPR=URLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1131)’))

certifiをimportしてurlopenの引数でcafile=certifi.where()を加える。

import certifi
...
urllib.request.urlopen("https://ambiesoft.com/", cafile=certifi.where())

import certifi

...

urllib.request.urlopen("https://ambiesoft.com/", cafile=certifi.where())
