Comparing int variables
I am trying to create some code that simulates the rolling of a stamp. I want the code to stop when it rolls 1, but my program keeps right on rolling that dies.
import random
def rollDie(die):
die = random.randint(1,6)
print(die)
die1 = 0
while die1 != 1:
rollDie(die1)
My suspicion is that my code is comparing object id 1 and object id die1. As far as I can tell, "! =" Is an appropriate "not equal" comparison operator.
So what am I doing wrong and how do I compare the values of a variable as opposed to their object id?

You need to update the value of die1, the easiest way to use your function is to go back into the function and assign the return value to die1:
def rollDie():
return random.randint(1,6)
die1 = 0
while die1 != 1:
die1 = rollDie()
print(die1)
die1 = rollDie()
will update every time through the loop, your code always keeps die1
its initial value 0
.
ints are immutable , so passing die1
to a function and setting die = random.randint(1,6)
won't change the original object, it will create a new object.
