I am Noob in Python. My Boss instructed me to run this python script with TOR proxy server running. He told me to pass this parameter this way: python DownloadYP.py /Users/myfolder/ japan http://www.jpyellow.com/company 1 222299
He configured it on MAC. I am using windows. So my parameter is this way: python DownloadYP.py C:\rrrb japan http://www.jpyellow.com/company 1 222299
But I am getting error:

I have downloaded TorVPN to run a Proxy server.. and running this script. So why the error is occurring? This is the script which can download a website.
The issue is in DownloadYP.py -
You do not have the files - C:\\rrr\japan\limit.txt
I would suggest creating a dummy file in the above directory with that name, and try running the script again.
Also, on a side note - You are mixing the os path separaters from unix and using it in windows , instead you need to use os.path.join() function so that python is able to handle the os path separaters accross platforms. The code would be like -
import os
self.dir = os.path.join(str(path),str(country))
Also, when openning the file, you need to use os.path.join , instead of directly specifying the path separators -
fin = open(os.path.join(self.dir,"limit.txt"),'r')
