python中，类属性为只读属性
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
--------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-33-91d30e8bb3c6> in <module>() ----> 1 pc2.name = 1 AttributeError: can't set attribute
pc2.name() # 加了@property，不能调用name()函数了
