Test Your Passwords

This is a little follow-up to the post about learning to program in python.
I thought I would throw some code out there for people to play with.

This program is written in python3. It prompts the user to enter a password that they want to test and compares it to complexity requirements and then checks if it is in a file called passwords.txt in the working directory.  It will tell the user if the password meets complexity requirements (currently set for windows' standard for complexity (8+ characters and 3 of the 4 categories: upper case, lower case, number or special characters)  There are some unused functions in this such as num_specials() that are there in case you want to customize it for stricter password requirements.

You will need to provide a passwords.txt file with one word per line of passwords that the user should not use. A good place to look for password lists is pastebin.com

If you are learning python then take a look at the code, run it in IDLE, play with the functions, see if you can extend it to do something cool.

If you are not learning python that's cool just place a password.txt file in the same directory full of words you don't think are good to use (The top 10 most used passwords is a start), and run it like so:

python3 passwordStrengthChecker.py

 Anyway, here is that code:
