Script Code that generates all Passwords - Python

I doubt you have the RAM or the time, but this is a python script I wrote to generate all password combinations in a given range. Outputs results to a .txt file. Just for fun. I ran it on an octa-core Linux box I had for a week and only got to ae----.

from itertools import *

fileOutput=1

minLength=6

maxLength=12

pwList = []

inputstr = "abcdefghijklmnopqrstuvwxyz"

inputstr = inputstr+"0123456789"+inputstr.upper()+"!#$%&'()*+-."

print inputstr

for lenPW in range(minLength,maxLength):

    perms = (p for p in product(inputstr,repeat=lenPW))

    for p in perms:

        print ''.join(p)

        tempString = "".join(p)

        if tempString not in pwList:

            pwList.append(str(tempString))

if fileOutput==1:

    outputFile = open("passwords.txt",'w')

    outputFile.writelines('\n'.join(''.join(items) for items in pwList))
