帶括號的扁平化嵌套 json (Python Pandas)

Question

我想尋求有關在括號內規范化 JSON 的任何建議。 我已經用 json_normalize 和一個用戶定義的 function 做了幾次嘗試來嵌套任何 JSON 直到現在它一直毫不費力地工作（感謝 Serge de Gosson de Varennes 的分享，謝謝。）但我一直遇到錯誤或用戶定義的函數沒有壓平下面的 json 數據。

這是 CSV 示例

csv 通過 Pandas 讀取，然后我嘗試將其壓平。

import pandas as pd

#credit for this amazing function below and work goes to Serge de Gosson de Varennes
def flatten_nested_json_df(df):
    df = df.reset_index()
    s = (df.applymap(type) == list).all()
    list_columns = s[s].index.tolist()

    s = (df.applymap(type) == dict).all()
    dict_columns = s[s].index.tolist()

    while len(list_columns) > 0 or len(dict_columns) > 0:
        new_columns = []

        for col in dict_columns:
            exploded = pd.json_normalize(df[col]).add_prefix(f'{col}.')
            exploded.index = df.index
            df = pd.concat([df, exploded], axis=1).drop(columns=[col])
            new_columns.extend(exploded.columns)  # inplace

        for col in list_columns:
            # print(f"exploding: {col}")
            df = df.drop(columns=[col]).join(df[col].explode().to_frame())
            new_columns.append(col)

        s = (df[new_columns].applymap(type) == list).all()
        list_columns = s[s].index.tolist()

        s = (df[new_columns].applymap(type) == dict).all()
        dict_columns = s[s].index.tolist()
    return df

df1 = pd.read_csv('stackexample.csv')
df1.head() # screenshot highlights data before flattening attempt

嘗試展平之前的數據 JSON

#attempt at flattening
df2 =  flatten_nested_json_df(df1)
df2.head()

嘗試展平后的數據 JSON

感謝您對此事的任何建議！ 我已經在這個問題上停留了很多天尋找替代方案

謝謝你的任何建議

您使用的 function 正在運行，但它需要數據采用正確的格式。 列items中的數據是字符串格式，您需要將其轉換回數據結構（列表和字典）。

# https://www.geeksforgeeks.org/python-convert-a-string-representation-of-list-into-list/
from ast import literal_eval
df["items"] = df["items"].apply(literal_eval)

所以正常使用DataFrame中的function即可。

flatten_nested_json_df(df)

Output：
