Question

我正在使用urlopen（）运行python 3中的代码：

url = "http://www.ksl.com"

import urllib.request
from urllib.request import Request, urlopen
from bs4 import BeautifulSoup

import ssl
print(ssl.OPENSSL_VERSION)

req = Request(url, headers={'User-Agent': 'Mozilla/5.0'})
html = urlopen(req).read()
html = html.decode('utf-8')

每次运行它都会弹出错误：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 1254, in do_open
    h.request(req.get_method(), req.selector, req.data, headers)

在处理上述异常期间，发生了另一个异常：

Traceback (most recent call last):

    html = urlopen(req).read()

看看类似的线程，我推断出与python一起使用的SSL版本可能是错误的，但是，我还没有能够解决问题，而且我没有足够的知道如何自己动手吧。

对我来说奇怪的是我没有改变任何关于我的电脑的事情，上周脚本运行正常！

是什么给出了？

运行python 3脚本时使用了错误的ssl版本
