Question

这是我在python3中的代码：

import pandas as pd

tables = pd.read_html("https://www.iitp.ac.in/index.php/departments/school-of-basic-sciences/chemistry/people/ug-student-chemistry.html")

print(tables)

我收到了这个错误：

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):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/pandas/io/html.py", line 906, in read_html

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

到目前为止，这一直都很顺利，但我在这个特定的网站上遇到了这个问题。此外，我是新手，并不太了解SSL证书，我在谷歌搜索它仍然没有太多的知识。

Answer 1

对于MAC
单击Applications =＆gt; Python然后双击Install Certificates.command。

Answer 2

使用-

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

使用pandas时出现错误urlopen错误[SSL：CERTIFICATE_VERIFY_FAILED]证书验证失败
