python - 如何将具有多个不同长度值的嵌套列表转换为python中的pandas数据框？

Question

我从 50 个 Twitter 帐户收集关注者 ID(每个帐户 1,000 到 25,000 个)，并且能够以类似于以下的格式将这些关注者 ID 存储在 json 中:

[
    36146779,
    [
        170742628,
        3597763396,
        13453212,
        24763726,
        19087188,
        19605181,
        37374972
    ],
    22971125,
    [
        1114702974,
        1145981566365130758,
        1118409958561685504,
        822439041312423941,
        1110524937788424197,
        807718095460581376,
        24763726,
        3181477874,
        1076870147980300288,
        307465302,
    ],
     24763726,
    [........

我想做的是找到所有相同的关注者ID，比如一个人24763726同时关注帐户36146779和22971125。关于如何解决这个问题有什么建议吗？我对 Python 和一般编程都很陌生，如果有任何帮助或建议，我将非常感激!

到目前为止，我能够将保存的数据(json 格式)转换为 pandas 数据框，但它不是我想要的形式。

import json
import pandas as pd

# Import the data
with open("2019_07_02_eco copy.json", "r", encoding="utf-8") as f:
    data_list = json.load(f)

# Create a pandas DataFrame with the follower ids 
df = pd.DataFrame(data_list)

print(df.head)

我期望的是一个 pd 数据框，其中帐户 ID(50 个帐户的)作为列标题，追随者 ID 位于其下面的行中。

我得到的是这样的:

[194 rows x 1 columns] 

<bound method NDFrame.head of                                                      0

Answer 1

试试这个:

data = [
    36146779,
    [
        170742628,
        3597763396,
        13453212,
        24763726,
        19087188,
        19605181,
        37374972
    ],
    22971125,
    [
        1114702974,
        1145981566365130758,
        1118409958561685504,
        822439041312423941,
        1110524937788424197,
        807718095460581376,
        24763726,
        3181477874,
        1076870147980300288,
        307465302,
    ],
    24763726,
    [
        1145981566365130758,
        1118409958561685504,
        822439041312423941,
        1110524937788424197,
        22971125
    ]
    ]

d = {}
for i in range(0,len(data)-1,2): # convert to dictionary
    d[str(data[i])] = data[i+1]

def getKeys(dictOfElements, valueToFind):
    listOfKeys = list()
    listOfItems = dictOfElements.items()
    for item  in listOfItems:
        if valueToFind in item[1]:
            listOfKeys.append(item[0])
    return  listOfKeys


for key in d.keys():
    keys = ",".join(getKeys(d, int(key)))
    print ("person: {}, follows accounts: {}".format(key, keys))

输出:

person: 36146779, follows accounts: 
person: 22971125, follows accounts: 24763726
person: 24763726, follows accounts: 36146779,22971125
