To access a nested dictionary value in Python, you need to: Access the dictionary inside of a dictionary by its key. Access the value of the accessed dictionary by the associated key.

Use reduce() to traverse the dictionary: return reduce(operator.getitem, mapList, dataDict) and reuse getFromDict to find the location to store the value for setInDict(): getFromDict(dataDict, mapList[:-1])[mapList[-1]] = value.
