完整文件为here供参考
我认为这段代码可以工作
import pandas as pd
from pandas import json_normalize
import json
with open('autarquicas_2021.json') as f:
data = json.load(f)
df = pd.json_normalize(data)
但是这会返回以下内容：
df.head()
Aveiro.Albergaria-a-Velha.candidates ... Évora.Évora.total_votes.percentageVoters
0 [{'effectiveCandidates': ['JOSÉ OLIVEIRA SANTO... ... 49.84
[1 rows x 4312 columns]
df.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 1 entries, 0 to 0
Columns: 4312 entries, Aveiro.Albergaria-a-Velha.candidates to Évora.Évora.total_votes.percentageVoters
dtypes: bool(308), float64(924), int64(1540), object(1540)
memory usage: 31.7+ KB
None
由于某种原因，代码无法正常工作，我的研究导致我没有找到解决方案，因为似乎每个 json 文件都有自己的想法。
任何帮助将不胜感激。提前感谢您！

【问题讨论】：
-
您希望数据看起来如何？
-
pd.read_json("your_json_file.json") 工作吗？
-
@HaleemurAli 我也应该发布它。在这里你可以看到一个例子，目标是docs.google.com/spreadsheets/d/e/…
-
@zabop pd.read_json 返回 ``` Aveiro Açores Beja Braga Bragança ... Setúbal Viana do Castelo Vila Real Viseu Évora Albergaria-a-Velha {'candidates': [{'effectiveCandidates': [ 'JOSÉ... NaN NaN NaN NaN ... NaN NaN NaN NaN NaN``` 带有 df.info() 返回
[2 rows x 20 columns] <class 'pandas.core.frame.DataFrame'> Index: 306 entries, Albergaria-a-Velha to Évora Data columns (total 20 columns): # Column Non-Null Count Dtype --- ------ -------------- ----- 0 Aveiro 19 non-null object -
所以，我使用了一个在线工具，这是生成的 CSV 文件：docs.google.com/spreadsheets/d/e/…
