[英]ValueError errors while reading JSON file with pd.read_json
我正在嘗試使用 Pandas 讀取 JSON 文件:
import pandas as pd
df = pd.read_json('https://data.gov.in/node/305681/datastore/export/json')
我得到ValueError: arrays must all be same length
其他一些 JSON 頁面顯示此錯誤:
ValueError: Mixing dicts with non-Series may lead to ambiguous ordering.
我如何以某種方式讀取值? 我並不特別關注數據有效性。
查看 json 它是有效的,但它嵌套了數據和字段:
import json
import requests
In [11]: d = json.loads(requests.get('https://data.gov.in/node/305681/datastore/export/json').text)
In [12]: list(d.keys())
Out[12]: ['data', 'fields']
您希望數據作為內容,字段作為列名:
In [13]: pd.DataFrame(d["data"], columns=[x["label"] for x in d["fields"]])
Out[13]:

另請參閱json_normalize
以獲取更復雜的 json DataFrame 提取。
下面列出了我的鍵值對:
from urllib.request import urlopen
import json
from pandas.io.json import json_normalize
import pandas as pd
import requests
df = json.loads(requests.get('https://api.github.com/repos/akkhil2012/MachineLearning').text)
data = pd.DataFrame.from_dict(df, orient='index')
print(data)
eht對於這種情況,我們可以通過執行來創建數據幀
import pandas as pd
df = pd.DataFrame(data["data"])
