Question

我有一个数据框，其中包含嵌套的字典项，我无法将该数据框存储到我的数据库中。它给我一个TypeError: sequence item 0: expected str instance, dict found的错误。有没有解决这个问题的方法

CODE：

df = pd.DataFrame.from_dict(mprofile,orient='index')

我的字典mprofile的输出是这样的：

如果您想要一种方式来呈现这一点，您可以将其写入数据库...使用json

import json

df.applymap(json.dumps)

                                                                   0
id                                               "10153836054533219"
birthday                                                "04/17/1993"

first_name                                                  "Faizan"
gender                                                        "male"
hometown           {"id": "111501225536407", "name": "Islamabad, ...
last_name                                                    "Ahmad"
link               "https://www.facebook.com/app_scoped_user_id/1...
location           {"id": "111501225536407", "name": "Islamabad, ...
locale                                                       "en_US"
name                                                  "Faizan Ahmad"
timezone                                                           5
updated_time                              "2017-03-20T19:32:12+0000"
verified                                                        true

这些现在都是json个字符串。
