Each time I try to write the code d.value in my console I get an error that says: " 'Die' object has no attribute 'value'

This is my code:

import random 

class Die:
  def __init__(self, sides=2, value=0):
      if not sides >= 2:
          raise ValueError("Must have at least 2 sides")
      if not isinstance(sides, int):
          raise ValueError("Sides must be a whole number")
          self.value = value or random.randint(1, sides) 

and this is what i code into the console:

from dice import Die
d = Die()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Die' object has no attribute 'value '

The line that creates self.sides is indented more than the video example. This causes it to be controlled by the "if" statement and located after the "raise" statement (which will prevent any code following from being executed).

Shift the indentation one stop left to get the behavior shown in the video.

ok that worked! I read the code hundred time and I don't know how I missed that simple error :0!

Thank you a lot..
