urllib.request.urlopen(URL) not working in python3

I am trying to access JSON using urllib.request.urlopen. It works fine when I use urllib2 in python2, but not urllib.request.urlopen.

URL = 'https://api.exchangeratesapi.io/latest'

f = urllib.request.urlopen(URL)

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 1316, in do_open

In my case there was an issue with error in request.py:

_load_windows_store_certs caused MemoryError

Fixed by updating python from version 3.7.4 to 3.8.1

Hope this help

This is what I used and it worked:

from urllib.request import urlopen

URL = 'https://api.exchangeratesapi.io/latest'
f = urlopen(URL)

I hope this works for you!

you can try to disable the ssl verification

import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
