SSLCertVerificationError while running the simplest of PubChemPy examples

[aromring]

The following example from PCP documentation: import pubchempy as pcp c = pcp.Compound.from_cid(5090) print(c.molecular_formula) results in `SSLCertVerificationError Traceback (most recent call last) File c:\Python312\Lib\urllib\request.py:1344, in AbstractHTTPHandler.do_open(self, http_class, req, **http_conn_args) 1343 try: -> 1344 h.request(req.get_method(), req.selector, req.data, headers, 1345 encode_chunked=req.has_header('Transfer-encoding')) 1346 except OSError as err: # timeout error

URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1000)>` I can browse to https://pubchem.ncbi.nlm.nih.gov/ without a problem and search for CID=5090 delivers rofecoxib. How to fix it? BTW, I am on Windows 10, not MAC
