Answer 1

您会感兴趣的是一个名为json的标准库：

import json

jstring = ##insert your json string here###

data = json.loads(jstring)

data将成为嵌套字典/列表的python对象。你应该从那里进行实验，找出如何访问你想要的东西。

如果您想撰写CSV，请查看csv：

import csv

data = ### a list of lists ###

with open('filename.csv', 'w') as f:
    csv.writer(f).writerows(data)

Answer 2

你可以这样做：

import json

data_list = json.loads(json_data)
ans_list = []
data_list = data['rows']
for row in data_list:
    ans_list.append(row['id'], row['interests'], row['name'], row['category'], row['created_time'])
print(ans_list)

从json中提取信息
