You can set proxies using environment variables   import os os environ  http proxy      127 0 0 1  os environ  https proxy      127 0 0 1    urllib2 will add proxy handlers automatically this way  You need to set proxies for different protocols separately otherwise they will fail  in terms of not going through proxy   see below   For example   proxy   urllib2 ProxyHandler   http    127 0 0 1    opener   urllib2 build opener proxy  urllib2 install opener opener  urllib2 urlopen  http   www google com     next line will fail  will not go through the proxy   https  urllib2 urlopen  https   www google com     Instead   proxy   urllib2 ProxyHandler        http    127 0 0 1        https    127 0 0 1     opener   urllib2 build opener proxy  urllib2 install opener opener    this way both http and https requests go through the proxy urllib2 urlopen  http   www google com   urllib2 urlopen  https   www google com
