Password Generator (Python recipe) by Alexander Thomas Cruz
ActiveState Code (http://code.activestate.com/recipes/577905/)

Generates a really strong and secure password. It uses multiple characters and symbols. Remember to score please! It really means a lot to me. Revision 4 includes an input so you can choose how many characters you want your password to have. It is also faster due to a suggestion by Garel Alex. Thanks!

import string, random

print "How many characters would you like the password to have?"
print "Must be nine or more"
length = input ()


password_len = length

password = []

for group in (string.ascii_letters, string.punctuation, string.digits):
    password += random.sample(group, 3)

password += random.sample(
                 string.ascii_letters + string.punctuation + string.digits,
                 password_len - len(password))

random.shuffle(password)
password = ''.join(password)


print password

Any suggestions?

Better than checking afterwards, meet the requirement from the begining :

import string, random

password_len = 30

password = []

for group in string.ascii_letters + string.punctuation + string.digits:
    password += random.sample(group, 3)

password += random.sample(
                 string.ascii_letters + string.punctuation + string.digits,
                 password_len - len(password))

random.shuffle(password)
password = ''.join(password)

sorry instead of:

for group in string.ascii_letters + string.punctuation + string.digits:

It is: 

for group in (string.ascii_letters, string.punctuation, string.digits):

Thank you for your code. Try looking at Generating And Checking Passwords In Python
