While using pandas got error urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

问题

This is my code in python3 :

import pandas as pd

tables = pd.read_html("http://http.com/")

print(tables)

And I got this error :

Traceback (most recent call last):

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)>

This have been working very well till now, but I have this problem on this particular website. Also, I am new in this and don't know much about SSL Certificate, I searched it on google and still do not have much knowledge about it.

回答1:

use -

import ssl

ssl._create_default_https_context = ssl._create_unverified_context
