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 …
