I want to get random number from 1 to 6 whenever i run this but i only get 1.

from random import randint

class die : def __init__(self): self.value = 1

def roll(self): self.value = randint(1,6)

def getvalue(self): return self.value

def __str__(self): return("the number on the die is {}".format(self.value))

t = die()

print(t)
