While loop doesn't stop looping

Question

I'm pretty new to python. I wrote this to emulate rolling dice;

dsides = int(input("how many sides do your dice have?"))
print("Your dice has " + str(dsides) +" sides")

dint = int(input("How many dice do you want to roll?"))
print("You are rolling " + str(dint) + " dice")

import random
y=0

while( y < dint ):
    out = random.randint(1, int(dsides))
    print(str(out))
    y+1

the problem is the while loop doesn't stop looping on integer 'dint' quantity....

That's because you didn't re assigned the y after increasing. change it to y=y+1 — Kasravnd

The last line should read

y=y+1

Now it is not doing anything to y.

(A general tip for debugging: If your loop does not terminate, print out the loop value to see what is happening to it)

We have all been there once ;-) - please mark the answer as accepted (which will also give you some so-points)

The problem debugging for me is that I can only do it via code. I'm coding at college and due to admin rights etc I can only use online consoles which never seem to include debugs.... So I knew the loop was stuck in a loop because it wasn't returning anything.

what about adding print(y) ?

Obiehakerman Over a year ago

Well I'm attempting to have it print a separate variable so that the output looks like this; Rolls: 3 - 2 - 5 -3 but I'm not to sure how to do that, don't know how to turn 'dint' into a numbered array, for instance if 'dint' = 4 I want an array 'arrrolls' = [1, 2 , 3, 4]

Of cource, when you've found and corrected the bug, you remove the debugging output.

You need to put y+=1 or y=y+1 at the end of the while.

Instead of this y+1 you have to do this y = y+1
