I am using Python 3.4 on Windows 7, and I am trying to test if a proxy allows or denies connections to particular websites by using a python script.
I am using the code below:
from urllib.request import Request, urlopen
from urllib.error import URLError, HTTPError, urllib
conf = "http://{}:{}#{}".format(login, password, proxy)
supp = urllib.request.ProxyHandler({"http": conf})
auth = urllib.request.HTTPBasicAuthHandler()
open = urllib.request.build_opener(supp, auth, urllib.request.HTTPHandler)
urllib.request.install_opener(open)
response = urlopen(Request("http://www.google.com"))
I get no errors when executing the code above, however as soon as I switch the URL to an HTTPS one (for example, https://www.google.com), I get the following error:
C:\Python34\python.exe test_url.py
Traceback (most recent call last):

raise URLError(err)

Any ideas why my code is only working with HTTP websites?
You need to specify the proxy handler for HTTPS separately, as it is a different protocol to HTTP. So the ProxyHandler line should be changed to:
supp = urllib.request.ProxyHandler({"http": conf, "https": conf})

i have a no idea about this error, please help me to solve this problem. Thank you....
The package is broken. See for example, this issue on GitHub: https://github.com/lukaszbanasiak/yahoo-finance/issues/148
Your best bet would be to indicate on GitHub that the package is not working and perhaps the author is able to help you further.
Hello everyone I am pretty new to programming so please forgive me any noob mistakes.
I am trying to use urllib in python 3.6 to find a string on a webpage and the solution I found here is working great for most webpages i tested, for example:
from urllib.request import urlopen
>>>string = 'google'
>>>url = 'https://google.com/'
>>>webp=urlopen(url).read()
>>>isfound = webp.find(string.encode('utf-8'))
>>>print(isfound)
186
But when I try using the URL https://chan.sankakucomplex.com/ (NSFW) I get tons of errors and I don't know why.
I allready tried changing my DNS to 8.8.8.8 but this didn't change anything.
error:

This tells me that your DNS server is refusing to translate the text address (chan.sankakucomplex.com) into an IP address. It's not an issue with Python.
Can you get to that site from a web browser running on the same machine where you're running your python code?
I am trying to make a python program that checks to see if the cost has changed or not for a website. However, every time I run the code it comes up with this python error below and then I can not access the site on any devices in the house for a period of time without is saying 'This site can’t be reached the site took too long to respond.'
Even though it doesn't load for me the website is still working
Code below
try:

Is it a bug or anything i missed?
C:\Users\user1\Desktop\scrape>python -V
Python 3.4.1
To the documentation! PEP 8, pretty much the be all end all on python code formatting, states "In Python, single-quoted strings and double-quoted strings are the same." This is written by the creator of Python, and I'm going to take his word for it.
Looking at your stack trace I see the error No connection could be ma
de because the target machine actively refused it, so maybe that means something wonky was going on with the server at that point?
