title: incrementally increase letters through the alphabet
body: <p>So I have been trying to create a simple bruteforce script for a php form (on my own local webserver of course), It essentially works by inputting data into the from an list through a for loop. Here is the problem; if my list is: <code>list = ['a','b','c','d','e','f','g']</code> and my for loop looks something like this:</p>
  
  <pre><code>for i in list:
     r = request.post(url, values) #posts the values
     if 'id=correct' in open('output.txt').read(): #check if it works
        print("logged in") 
        #if it works, it would print this, if not, 
        #it will retry with the next element in the list
  </code></pre>
  
  <p>The problem is, this will work for only one letter passwords (as it only cycles through the list once). My question is; how would I get it so that once it cycles through the list once, it will start the for loop again except with two elements from list(ie, aa,ab,ac,ad,ae,ef etc.)</p>
  
  <p>Thanks!</p>
