python创建多维字典方法

python不直接创建多维字典，需要逐层判断不存在创建，存在追加：

例如：

不能直接

dictName['key1']['key2']['key3']['key4']['key5'] =?['123','456']

?

下面函数实现：

def createDict(tupleVals,val):
    tupNum = len(tupleVals)
    tempName = dictName = {}
    for index,tupleVal in enumerate(tupleVals):
        if index == tupNum - 1:
            dictName[tupleVal] = val
        else:
            if tupleVal not in dictName.keys():
                dictName[tupleVal] = {}
            else:
                dictName.update({tupleVal: {}})
        dictName = dictName[tupleVal]
    return  tempName

dictName = createDict(('key1','key2','key3','key4','key5'),['123','456'])
print(dictName['key1']['key2']['key3'])
