Question

在我开始之前是我的Python代码，我试图从网上下载一个图像（我只是习惯使用Python，而不是出于任何特定原因）。

import random
import urllib.request

def download_web_image(url):
    name = random.randrange(1, 1000)
    full_name = str(name) + '.jpg'
    urllib.request.urlretrieve(url, full_name)

download_web_image('https://www.thenewboston.com/photos/users/2/resized/a403d4e7fb26d7373009c97d68b2448b.jpg')

但是，当我运行代码时，会出现此错误：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 1240, 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：

    raise URLError(err)
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:646)>

IDLE和pycharm都会发生这种情况。我做错了什么？

如何允许python（特别是pycharm）接受传入的SSL证书？
