from random import randint tal = ['0','1','2','3','4','5','6','7','8','9'] sign = ['@','£','$','€','&', '!', '?', '!'] bogstaver = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',              'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'x', 'y', 'z']    numbers = [tal[randint(0,9)] + sign[randint(0,7)] + bogstaver[randint(0,24)] + tal[randint(0,9)] x in range(4)] password = "".join(numbers) print(password[2::8])  print(password)
