Python com Proxy [resolvido]

[pedropehrson]

Ola pessoal tudo bem?

Estou com um problema em um script em python que nao consegue passar pelo  proxy.

Acredito eu que o python tenh que setar um proxy por ele direto, ele nao puxa o proxy do sistema.

bom o script é esse aqui:


import urllib2
import sys

if sys.argv > 1: #arg must be supplied
       stocks = sys.argv #args are the stocks
       stocks.pop(0) #pop the first entry since its the filename
       print
       print '%5s %8s %9s %9s %9s' % ('Name','Value','Open','Change','Time') #print header
       print '--------------------------------------------' #fancy line

       for i in stocks: #for each stock do this
               stock=i

               #This is the url from yahoo...if this changes the script dies, Ill fix it and upload again if it happens.
               csv = urllib2.urlopen('http://download.finance.yahoo.com/d/quotes.csv?s='+ stock +'&f=sl1d1t1c1ohgv&e=.csv')
               #csv = urllib2.urlopen('http://download.finance.yahoo.com/d/quotes.csv?s=CAKE&f=sl1d1t1c1ohgv&e=.csv')
               data = csv.read() #grab csv
               tokens = data.split(',') #split into tokens

               name=tokens[0].replace('"','') #get rid of quotes
               value=tokens[1]
               time=tokens[3].replace('"','')
               change=tokens[4]
               openVal=tokens[5]

               print '%5s' % name,'%8s'% value,'%9s'% openVal,'%9s'% change,'%9s'% time #print to screen with formatting
else:
       print 'You forgot to supply your stock quote as an arg' #go back and give the script your stocks as arguments
       print 'Example: python stocks.py goog'


Eu consigo chamar ele normalmente na rede sem proxy, porem com a rede com proxy acontece essa msg aqui:

Alguem sabe como é que coloca proxy no python? Cheguei a abrir o urllib2.py mas nao achei um lugar certo para "proxyar"


Fico no aguardo galera, abcs
