TypeError: list indices must be integers or slices, not tuple

i followed a tutorial on youtube to create a snake game in python via Visual Studio code! this is the error message i keep getting when i press a key to play the game, wondering how to fix. Line of code causing error: self.turns[self.head.pos[:]] = [self.dirnx, self.dirny]

self.turns.append(self.dirnx) self.turns.append(self.dirny)

so the code should look like: for key in keys: if keys[pygame.KEY_LEFT]: self.dirnx = -1 self.dirny = 0 self.turns.append[self.head.pos[:]] = [self.dirnx, self.dirny]

I made the adjustments you suggested, my game window is not closing any more when I press the key to play. Now i assume i need to do something else within the Def Main() Call to accommodate for the changes i just made

def move(self, dirnx, dirny): self.dirnx = dirnx self.dirny = dirny self.pos = (self.pos[0] + self.dirnx, self.pos[1] + self.dirny) this is the move code
