问题描述
我想知道,如果你能在attibute添加到Python字典。
I was wondering if you could add an attibute to a python dictionary.
class myclass(): def __init__(): self.mydict = {} #initialize a regular dict self.mydict.newattribute = "A description of what this dictionary will hold" >>>AttributeError: 'dict' object has no attribute 'newattribute' setattr(self.mydict,"attribute","A description of what this dictionary will hold" >>>AttributeError: 'dict' object has no attribute 'newattribute'反正是有迅速增加我的描述属性,而无需复制dict类和重载的构造函数。我认为这将是简单的,但我想我错了。
Is there anyway to quickly add my description attribute without having to copy the dict class and overloading the constructor. I thought it would be simple, but I guess I was wrong.
谢谢,Ĵ
推荐答案刚刚从获得字典:
class MyDict(dict): passMyDict 的实例可以有自定义属性:
Instances of MyDict can have custom attributes:
>>> d = MyDict() >>> d.my_attr = "whatever" >>> d.my_attr 'whatever'更多推荐
