Hi Guys!

I trying out the code that was written in this lesson https://null-byte.wonderhowto.com/forum/nullforce-web-based-login-cracker-0137165/ (you can find the code here below) on how to build a web based login cracker, but it keeps giving me the same error.. there's someone who can help me? Thank you a lot

here is the error message:

This insted is the code:

import re, urllib, urllib2

words = open(wl, "r").readlines()
print "+ Words loaded:", len(words)

for word in words:
word = word.replace("\n","")##This will remove newlines.
