Python 3 SOCKSIPY Module prints error - sockets

Question

I downloaded the socks.py file and placed it in the python lib folder. When I run this script:
import socks
import socket
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "localhost", 9150)
socket.socket = socks.socksocket
import requests
from bs4 import BeautifulSoup
url = 'http://www.google.ca'
r = requests.get(url)
soup = BeautifulSoup(r.content)
print (soup)
it sends an error like this:
Traceback (most recent call last):

Can someone help me? I do not know how to fix this.. No where explains what I need to do in this case. Thank you very much
