i am trying to connect to TOR through python but it doesnt let me the code is:
def tor_connection():
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "127.0.0.1", 9050, True)
socket.socket = socks.socksocket
def main():
tor_connection()
print('Connected to tor')
con = httplib.HTTPConnection('myip.dnsomatic.com/')
con.request('GET', '/')
response = con.getresponse()
print(response.read())
main()
even though its giving me the next error message:
Traceback (most recent call last):

i am just a beginner could someone help me out please? i have tried it in another laptop but its the same error message
It's not a problem of socks. You need to specify the hostname without the trailing /:
>>> # with /
>>> httplib.HTTPConnection('myip.dnsomatic.com/').request('GET', '/')

I am trying to open a URL using the following code:

I've searched for [Errno -3] and I also looked into "https://docs.python.org/3/library/urllib.request.html" but I didn't find anything useful.
What am I doing wrong?
I wanted to use you-get to download videos, but when I use it after I installed it, an error ocurred:
my python3.9 is well installed and I have checked the system path. I have also used many ways to install you-get including using pip3, downloading the zip from github and this error always occur. I thought this problem could be caused by my vpn, but when I close vpn, nothing changed.
I opened cmd with administrator as well.
I typed this command: you-get 'https://www.youtube.com/watch?v=nWQwrU1qUrc' --debug

could someone help me pls, thank you so much
If you're intent on using cmd, you should replace ' with " in your command, or since the website contains no spaces anyway, just remove the quotes. So try running:
you-get "https://www.youtube.com/watch?v=nWQwrU1qUrc"
OR
you-get https://www.youtube.com/watch?v=nWQwrU1qUrc
However in the future I'd suggest you just use Windows PowerShell it's much better in my opinion.
UPDATE: I managed to do a request with urllib2, but I'm still wondering what is happening here.
I would like to do a HTTPS request with Python.
This works fine with the requests module, but I don't want to use external dependencies, so I'd like to use the standard library.
httplib
When I follow this example I don't get a response. I get a timeout instead. I'm out of ideas as to what would cause this.
Code:
import requests
print requests.get('https://python.org')
from httplib import HTTPSConnection
conn = HTTPSConnection('www.python.org')
conn.request('GET', '/index.html')
print conn.getresponse()
Output:
<Response [200]>

raise err
socket.error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
urllib
This fails for a different (but possibly related) reason. Code:
import urllib
print urllib.urlopen("https://python.org")
Output:
Traceback (most recent call last):
File "test.py", line 10, in <module>

What is requests doing that makes it succeed where both of these libraries fail?
requests.get without timeout parameter mean no timeout at all.
httplib.HTTPSConnection accept parameter timeout in Python 2.6 and newer according to httplib docs. If your problem was caused by timeout, setting high enough timeout should help. Please try replacing:
conn = HTTPSConnection('www.python.org')
with:
conn = HTTPSConnection('www.python.org', timeout=300)
which will give 300 seconds (5 minutes) for processing.

Your code doesn't work because the "host" argument expects just a hostname and not a url.
If you change it to:
driver = vcloud("login", "passwd", host="portal.vcloud")
it should work.
