代码如下:

class LastOfUs:
	def play(self):
		print("this Last Of Us is really funny")
class Uncharted:
	def play(self):
		print("the Uncharted is really funny")
class PsGame:
	def play(self):
		print("PS has many games")
class GameFactory:
	games = {"last_of_us": LastOfUs, "uncharted": Uncharted}
	def __new__(cls, name):
		if name in cls.games:
			return cls.games[name]()
		return PsGame()
uncharted = GameFactory("uncharted")
last_of_us = GameFactory("last_of_us")
uncharted.play()
last_of_us.play()
"""
the Uncharted is really funny
this Last Of Us is really funny
"""
