Two players share a class variable, and one of them gets its own value with setattr. class Player: team = "red" def __init__(self, name): self.name = name def __str__(self): return f"{self.name}/{self.team}" a = Player("Ana") b = Player("Ben") setattr(b, "team", "blue") Player.team = "green" print(a, b, len(vars(a)), len(vars(b))) What does the program print?
