I am trying to connect to Vcloud using lib cloud, the authentication works fine using rest API from firefox, but fails in python. am I missing something?

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.

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]>
Traceback (most recent call last):

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>
print urllib.urlopen("https://python.org")

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.

Also my code is :
import random
import urllib
def downloadWebImage(url):
name = random.randrange(1,1000)
fullName = str(name) + '.jpg'
urllib.urlretrieve(url, fullName)
downloadWebImage("https://qph.ec.quoracdn.net/main-qimg-601accaf841bba9145d3c46bece1ea10-p")
So what are the errors, why are they occuring? What is their fix?
I'm trying to run the following program, following a tutorial. How should I fix the error shown below?
import re
import urllib
#name=raw_input('Enter URL for the site name:')
handle=urllib.urlopen('http://www.iitk.ac.in')
for line in handle:
print line.strip()

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:

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', '/')
