Python 遍历类的dictionary属性

有人能为这个极简主义的例子提供一个合适的解决方案吗？我想遍历类的dictionary字段：

class MyClass:

    _a_dic : dict

    def __init__(self, a_dic : dict = None):
        if a_dic:
            self._a_dic = a_dic
        else:
            self._a_dic = {}

    @property
    def a_dic( self ):
        return self._a_dic

    def __iter__(self):
        ???

    def __next__(self):
        ???

bruh = MyClass( {'one' : 1, 'two' : 2} )

print( [ t for t in bruh ] )
> ['one', 'two']

print( [ bruh[t] for t in bruh ] )
> [1, 2]

---

我还想了解如果我使用列表而不是字典，这将如何工作。

只需实现

\uuuuu iter\uuuuuu

就可以委托给该指令

class MyClass:

    _a_dic : dict

    def __init__(self, a_dic : dict = None):
        if a_dic:
            self._a_dic = a_dic
        else:
            self._a_dic = {}
    
    def __iter__(self):
        return iter(self._a_dic)
