【工具封装】给 Python 字典加上点语法，实现 对象.属性 调用

一、序言：

  今天小编给大家封装了一个魔法工具，用了这个工具就能将 Python 中的字典类型数据，实现对象.属性的语法，开发时使用起来非常方便，还在等什么？赶紧收藏+点赞+关注吧 ！！！

    - 功能：为字典加上点语法，实现 对象.属性 调用。
    - 例如:
    >>> d = Struct({'age':18})
    >>> d.age
    >>> 18
    >>> d.gender
    >>> None

        # Your __getattr__ is being called with "__getstate__" to find that magic method,
        # and returning None instead of raising AttributeError as it should.
        if name.startswith('__'):
            raise AttributeError

    def __setattr__(self, name, val):
        self[name] = val

    def __hash__(self):
        return id(self)
