Question

my code passed, but I don't understand why. I thought tuples were immutable. Howcome I was able to do a += 1 on self.current_score[0] and change it ?

my code:

class Game: def init(self): self.current_score = [0, 0]

def score(self, player):
    if player == 1:
        self.current_score[0] += 1 
    if player == 2:
        self.current_score[1] += 1

game.py

class Game:
  def __init__(self):
    self.current_score = [0, 0]

Hi Rod,

self.current_score is a list rather than a tuple, indicated by the brackets. That's why you're able to change it.
