In Python, class properties are read-only properties

class Computer: """电脑""" # __slots__ = (‘_name‘, ‘mem‘, ‘cpu‘) def __init__(self, name, mem, cpu): self._name = name self.mem = mem self.cpu = cpu @property def name(self): # 只读， getter方法 return self._name def play(self, game=‘qq游戏‘): print(‘play‘, game)pc2 = Computer(‘admin‘, ‘8G‘, 8)

pc2.name   # name()函数变成属性了，

‘admin‘

pc2.name = 1  # 不能修改属性
