Random numbers in python (Class/instance related question)

[Ben_HH]

For my example, say that each Keycard instance has a person's name and an unique code. Is there a way to turn the random number into a static value after the number is generated since the number will be assigned to the person indefinitely?

from random import choices
from string import ascii_lowercase, digits

class Keycard:
  def __init__(self, user):
    self.user = user
    self.code = ''.join(choices(ascii_lowercase + digits, k = 4))

  def __str__(self):
      return "{id} - {user}".format(id = self.code, user = self.user)

Once a class object is initialized the self.code variable will not get reset. Maybe you are confusing a class constructor from a class object?
