I deleted my python 2.7 and installed the new 3.X version(conda). Then the urlopen just did not work.
from urllib.request import urlopen
html = urlopen("http://www.google.com/")
returns URLError: urlopen error [Errno 10093] getaddrinfo failed. What I am trying to do is urlretrieve('http://cfe.cboe.com/Publish/ScheduledTask/MktData/datahouse/CFE_U17_VX.csv')
But it returns the same error. The csv file can be download from chrome url easily. Help plz!
