    def __init__(self, sides=2):
        if sides < 2:
            raise ValueError("Can't have fewer than two sides")
        self.sides = sides
        self.value = random.randint(1, sides)

    def __int__(self):
        return self.value

    def __add__(self, other):
        return int(self) + other

    def __radd__(self, other):
        return self + other
class D20(Die):
    def __init__(self):
        super().__init__(sides=20)
hands.py
from dice import D20

class Hand(list):
    def __init__(self):
        super().__init__(size=2,die_class=D6)

    def roll(self,size,die_class):  
        for _ in range(size): # aici creem obiectele importate din clasa de D6(zarurile)
            self.append(die_class())
        self.sort()

    def _by_value(self,value):
        dice=[]
        for die in self:
            if die == value:

Here's a few hints:

  • you may not need to override __init__
  • you should also not need a _by_value method
  • the roll method does need a size argument, but it should not require any other argument(s)
  • the roll method will be used to create instances, so it might help to make it a class method
  • you won't need to sort anything
