深入了解嵌套字典

Question

这是一个很菜鸟的问题，请见谅。

谁能帮我深入了解嵌套字典。

我想知道如何访问字典“数据”（请参阅 link 中的数据）以便我可以对其进行分析。

非常感谢。

我正在使用 jupyter notbooks。

这是我目前拥有的：

import json
import pandas as pd

with open('./source/small_data_clean.json') as access_json:
    read_content = json.load(access_json)


type(read_content)

data_access = read_content['data']
data_access

Answer 1

您必须继续访问每个级别的密钥：

例如：

data_access['data']
data_access['data']['0']
data_access['data']['0']['Pi']

Answer 2

你必须迭代访问字典中的元素，这里是一个工作示例；

# TODO: Access, "data" -> "0" -> "Vi" -> "Diff"

def index_nested_dict(dict: dict, keys: list):
    for key in keys:
        dict = dict[key]

    return dict

test_dict = {
    "total": 1498,
    "state": "0",
    "limit": 10,
    "offset": 0,
    "data": {
