kaggle_environments使用的实现是一个名为structify的函数。

class Struct(dict):
    def __init__(self, **entries):
        entries = {k: v for k, v in entries.items() if k != "items"}
        dict.__init__(self, entries)
        self.__dict__.update(entries)

    def __setattr__(self, attr, value):
        self.__dict__[attr] = value
        self[attr] = value

# Added benefit of cloning lists and dicts.
def structify(o):
    if isinstance(o, list):
        return [structify(o[i]) for i in range(len(o))]
    elif isinstance(o, dict):
        return Struct(**{k: structify(v) for k, v in o.items()})
    return o

这可能有助于在《ConnectX》等游戏中测试AI模拟代理

from kaggle_environments import structify

obs  = structify({ 'remainingOverageTime': 60, 'step': 0, 'mark': 1, 'board': [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]})
conf = structify({ 'timeout': 2, 'actTimeout': 2, 'agentTimeout': 60, 'episodeSteps': 1000, 'runTimeout': 1200, 'columns': 7, 'rows': 6, 'inarow': 4, '__raw_path__': '/kaggle_simulations/agent/main.py' })

def agent(obs, conf):
  action = obs.step % conf.columns
  return action

最简单的解决方案。

定义一个只有pass语句的类。为该类创建对象并使用点表示法。

class my_dict:
    pass

person = my_dict()
person.id = 1 # create using dot notation
person.phone = 9999
del person.phone # Remove a property using dot notation

name_data = my_dict()
name_data.first_name = 'Arnold'
name_data.last_name = 'Schwarzenegger'

person.name = name_data
person.name.first_name # dot notation access for nested properties - gives Arnold

派生自dict和并实现__getattr__和__setattr__。

或者你也可以用Bunch，非常相似。

我不认为这是可能的monkeypatch内置字典类。

这是一个老问题，但我最近发现sklearn有一个可通过键访问的实现版本字典，即Bunch https://scikit-learn.org/stable/modules/generated/sklearn.utils.Bunch.html#sklearn.utils.Bunch

这也适用于嵌套字典，并确保后面追加的字典行为相同:

class DotDict(dict):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # Recursively turn nested dicts into DotDicts
        for key, value in self.items():
            if type(value) is dict:
                self[key] = DotDict(value)

    def __setitem__(self, key, item):
        if type(item) is dict:
            item = DotDict(item)
        super().__setitem__(key, item)

    __setattr__ = __setitem__
    __getattr__ = dict.__getitem__

我喜欢Munch，它提供了很多方便的选项在点访问。

进口蒙克 Temp_1 = {'person': {' fname': 'senthil'， 'lname': 'ramalingam'}} Dict_munch = munch.munchify(temp_1) dict_munch.person.fname
