    So, on pythonista. Well, you see, I am running a dictionary password cracker for science fair. It would really help if I can use it on iPad so I can test at lunch. However, it will not recognize the passwords.txt directory that I added in the folder with it. How to I set that?

    Copy of what I am running:
        [`enter code here`#!/usr/bin/python
    
    # This program is offered for use with the Science Buddies project idea
    # "How Easily Can Your Password Be Hacked?" which lets you explore the
    # makeup of a good password. This program will help you understand some
    # methods that people use to guess other people's passwords.
    #
    # the program begins execution at 'main' after the helper programs and functions
    # are defined. You'll also notice that several functions have places where 
    # print() functions have been turned into comments. When debugging a program, it's
    # helpful to add in more descriptive screen output than you might want later on.
    # Once the program is working, you can remove the extra output os, as we've done here,
    # 'comment it out' so that someone else can use it again later on if they decide to 
    # modify your program.
    
    #Tell Python we want to use some functions it doesn't always use

    from array import *

    # a selection below.

    #--------------- extra helper functions -------------------
    # These will be used by our search routines later on. We'll get these defined and out
    # of the way. The actual search program is called "main" and will be the last one
    # defined. Once it's defined, the last statement in the file runs it.

    I would like to know if there is any way to link a text file to a script so that it recognizes it and runs it. It won't recognize my passwords.txt file, a nd indeed that to execute the script.

    The copy part is not part of the scripts. This is the error code I receive. IOError: [errno 2] No such file or directory 'passwords.txt'

Internal error.

Oops! Looks like something went wrong!
