##Write a password generator in Python. Ask the user how strong they want their
##passport to be. Be creative with how you generate passwords - strong
##passwords have a mix of lowercase letters, uppercase letters, numbers,
##and symbols. The passwords should be random, generating a new password
##every time the user asks for a new password. Include your run-time code
##in a main method.

import random

#There are 3 lists, each adding a level of strength to the password
letter_mix = list("qwertyuiopasdfghjklzxcvbnm")
letter2_mix = list("QWERTYUIOPASDFGHJKLZXCVBNM")
symbol_mix = list("1234567890`+,.-^*<>;:_'?")
merged_list = letter_mix + letter2_mix
merged_list2 = merged_list + symbol_mix

human = input("How long do you want your passport to be? (4-9)")

def password_generator(x):
        human2 = raw_input("How strong do you want your passport to be? (strong/medium/weak)")
        if human2 == "weak":
            list_random = random.sample(letter_mix, x)
            list2 = ''.join(list_random)
            print list2
        elif human2 == "medium":
            list_random = random.sample(merged_list, x)
            list2 = ''.join(list_random)
            print list2
        elif human2 == "strong":
            list_random = random.sample(merged_list2, x)
            list2 = ''.join(list_random)
            print list2
        else:
            print "Sorry, that was not one of the options. Please tape either 'weak', 'medium' or 'strong'"

        continuar = raw_input("Do you want to generate another passport? (y/n)")
        if continuar == "y":
            b = True
        elif continuar == "n":
            b = False
            print "See you soon"
        else:
            print "Sorry, that was not one of the options"
