Setting proxy to urllib.request (Python3)

How can I set proxy for the last urllib in Python 3. I am doing the next

from urllib import request as urlrequest
ask = urlrequest.Request(url)     # note that here Request has R not r as prev versions
open = urlrequest.urlopen(req)
open.read()

I tried adding proxy as follows :

ask=urlrequest.Request.set_proxy(ask,proxies,'http')

However I don't know how correct it is since I am getting the next error:

336     def set_proxy(self, host, type):
--> 337         if self.type == 'https' and not self._tunnel_host:
    338             self._tunnel_host = self.host
    339         else:

AttributeError: 'NoneType' object has no attribute 'type'

You should be calling set_proxy() on an instance of class Request, not on the class itself:

from urllib import request as urlrequest

proxy_host = 'localhost:1234'    # host and port of your proxy
url = 'http://www.httpbin.org/ip'

req = urlrequest.Request(url)
req.set_proxy(proxy_host, 'http')

response = urlrequest.urlopen(req)
print(response.read().decode('utf8'))

I needed to disable the proxy in our company environment, because I wanted to access a server on localhost. I could not disable the proxy server with the approach from @mhawke (tried to pass {}, None and [] as proxies).

This worked for me (can also be used for setting a specific proxy, see comment in code).

import urllib.request as request

# disable proxy by passing an empty
proxy_handler = request.ProxyHandler({})
# alertnatively you could set a proxy for http with
# proxy_handler = request.ProxyHandler({'http': 'http://www.example.com:3128/'})

opener = request.build_opener(proxy_handler)

url = 'http://www.example.org'

# open the website with the opener
req = opener.open(url)
data = req.read().decode('utf8')
print(data)
