this is a script to get the rank of domains from alexa
usage: script.py input_domains.txt output.txt
it gets the domain from input, posts in alexa and gets the rank value
then it sort's the results in output.txt according to the rank
the less the rank is the more value is the domain, first apears on the list

the thing is when it times out connecting to alexa in the process, it gives this error:
http://pastebin.com/mkhgmabs
the script crashes and the output cames out empty

so i need to correct this as i can't get a full list rank sorted because it gets the error sometime in the process and all the work is lost
