Python class run once

(sorry for my english)

Guys, my class in Pyhton runs once

import csv, random
class myPassword:
        azlower = "abcdefghijklmnopqrstuvwxyz"
        azupper = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        vowel = "aeiouAEIOU"
        simbol = "!@#$%*"

        passw = random.sample(range(9), 2)
        passw = ''.join(map(str, passw))
        passw += random.choice(simbol)
        passw += random.choice(azupper)
        passw += random.choice(vowel)
        passw += random.choice(azlower)
        passw += random.choice(simbol)
        passr = random.sample(range(9), 3)
        passw += ''.join(map(str, passr))

for i in range (0,2):
        print (myPassword.passw)

This code runs the same password in every for. How to run the class again? Tkx!
