我有一个复杂的字典结构,我想通过一个键列表访问,以解决正确的项目.

dataDict = {
    "a":{
        "r": 1,
        "s": 2,
        "t": 3
        },
    "b":{
        "u": 1,
        "v": {
            "x": 1,
            "y": 2,
            "z": 3
        },
        "w": 3
        }
}    

maplist = ["a", "r"]

要么

maplist = ["b", "v", "y"]

我已经制作了以下代码,但是我确信如果有人有想法,有更好更有效的方法.

# Get a given data from a dictionary with position provided as a list
def getFromDict(dataDict, mapList):    
    for k in mapList: dataDict = dataDict[k]
    return dataDict

# Set a given data in a dictionary with position provided as a list
def …

有这样的字典

my_pets = {
    'Rudolf': {
        'animal': 'cat', 
        'legs': 4
    }
}

达到低于同等水平的较干净方法是什么？

my_pets['Rudolf']['legs']['front-right']['injured'] = True
my_pets['Rudolf']['legs']['front-left']['injured'] = False

它应该更新为

my_pets = {
    'Rudolf': {
        'animal': 'cat', 
        'legs': {
            'front-right': {'injured':True},
            'front-left': {'injured':False}
        }
    }
}
