Python 要输出CSV文件的已刮取json数据

所以我收集了这些数据

[
    {
        "id": 4321069,
        "points": 52535,
        "name": "Dennis",
        "avatar": "",
        "leaderboardPosition": 1,
        "rank": ""
    },
    {
        "id": 9281450,
        "points": 40930,
        "name": "Dinh",
        "avatar": "https://uploads-us-west-2.insided.com/koodo-en/icon/90x90/aeaf8cc1-65b2-4d07-a838-1f078bbd2b60.png",
        "leaderboardPosition": 2,
        "rank": ""
    },
    {
        "id": 1087209,
        "points": 26053,
        "name": "Sophia",
        "avatar": "https://uploads-us-west-2.insided.com/koodo-en/icon/90x90/c3e9ffb1-df72-46e8-9cd5-c66a000e98fa.png",
        "leaderboardPosition": 3,
        "rank": ""

And so on... Big leaderboard of 20 ppl

用这个代码擦掉

import json
import requests
import pandas as pd

url_all_time = 'https://community.koodomobile.com/widget/pointsLeaderboard?period=allTime&maxResults=20&excludeRoles='

# print for all time:

data = requests.get(url_all_time).json()
# for item in data:

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

for item in data:
    print(item['name'], item['points'])

我希望能够创建一个表来处理这个问题

每次我刮取数据时，我都希望它用标记为标题的新数据更新表中的点数。所以基本上我想的是，我的索引=用户名，标题=日期。问题是，我甚至无法创建具有该名称/点列的csv文件

到目前为止，我唯一成功的做法是将所有数据写入csv文件。我无法在print命令中找到我想要的数据

编辑：在阅读了@Shijith发布的内容后，我成功地将数据传输到了.csv，但考虑到我的想法（随着时间的推移添加更多数据），我问自己应该使用索引还是不使用索引来编写代码

与

没有

import pandas as pd

url_all_time = 'https://community.koodomobile.com/widget/pointsLeaderboard?period=allTime&maxResults=20&excludeRoles='
data = pd.read_json(url_all_time)
table = pd.DataFrame.from_records(data, columns=['points','name'])

table.to_csv('products.csv', index=False, encoding='utf-8')

您是否尝试过直接将json读入数据帧？从这里可以很容易地按照您的意愿对其进行转换。您可以为今天的日期添加一列并对其进行透视

import pandas as pd
url_all_time = 'https://community.koodomobile.com/widget/pointsLeaderboard?period=allTime&maxResults=20&excludeRoles='
df = pd.read_json(url_all_time)

data['date'] = pd.Timestamp.today().strftime('%m-%d-%Y')
data.pivot(index='name',columns='date',values='points')

@NoobAtPython更新了。在末尾的另一列“date”中输出相同的内容。这是我想要的一部分。我将进一步研究熊猫数据框功能

import pandas as pd
url_all_time = 'https://community.koodomobile.com/widget/pointsLeaderboard?period=allTime&maxResults=20&excludeRoles='
df = pd.read_json(url_all_time)

data['date'] = pd.Timestamp.today().strftime('%m-%d-%Y')
data.pivot(index='name',columns='date',values='points')
