將Google Maps api json標准化為pandas df

[英]normalize google maps api json to pandas df

我使用了Google Maps API來獲取美國國家公園的數據。 我正在嘗試將此數據標准化為pandas數據框。

但是,這不起作用: table = pd.io.json.json_normalize(park_json)並生成如下表: 在此處輸入圖片說明

我最初嘗試僅對結果列進行規范化,但會出現此錯誤:TypeError:列表索引必須為整數或切片,而不是str

然后我嘗試了:`new_table = pd.read_json((table ['results'])。to_json(),orient ='index')'但它出錯了:ValueError:數組必須都具有相同的長度

有什么建議么? 謝謝!!!

范例json: {'status': 'OK', 'results': [{'formatted_address': 'Acadia National Park, Mt Desert, ME 04660, USA', 'types': ['establishment', 'park', 'point_of_interest'], 'place_id': 'ChIJJSmiDrKjrkwRhFVV_A4i32I', 'address_components': [{'types': ['establishment', 'point_of_interest'], 'long_name': 'Acadia National Park', 'short_name': 'Acadia National Park'}, {'types': ['locality', 'political'], 'long_name': 'Mount Desert', 'short_name': 'Mt Desert'}, {'types': ['administrative_area_level_2', 'political'], 'long_name': 'Hancock County', 'short_name': 'Hancock County'}, {'types': ['administrative_area_level_1', 'political'], 'long_name': 'Maine', 'short_name': 'ME'}, {'types': ['country', 'political'], 'long_name': 'United States', 'short_name': 'US'}, {'types': ['postal_code'], 'long_name': '04660', 'short_name': '04660'}], 'geometry': {'location_type': 'APPROXIMATE', 'location': {'lng': -68.2733346, 'lat': 44.3385559}, 'viewport': {'southwest': {'lng': -68.4344785, 'lat': 44.2350589}, 'northeast': {'lng': -68.1591412, 'lat': 44.40370240000001}}}}]} {'status': 'OK', 'results': [{'formatted_address': 'Adams National Historical Park, 1250 Hancock St, Quincy, MA 02169, USA', 'types': ['establishment', 'museum', 'park', 'point_of_interest'], 'place_id': 'ChIJbbPB5rB844kR7hOzzjBr4Cs', 'address_components': [{'types': ['establishment', 'point_of_interest'], 'long_name': 'Adams National Historical Park', 'short_name': 'Adams National Historical Park'}, {'types': ['street_number'], 'long_name': '1250', 'short_name': '1250'}, {'types': ['route'], 'long_name': 'Hancock Street', 'short_name': 'Hancock St'}, {'types': ['locality', 'political'], 'long_name': 'Quincy', 'short_name': 'Quincy'}, {'types': ['administrative_area_level_2', 'political'], 'long_name': 'Norfolk County', 'short_name': 'Norfolk County'}, {'types': ['administrative_area_level_1', 'political'], 'long_name': 'Massachusetts', 'short_name': 'MA'}, {'types': ['country', 'political'], 'long_name': 'United States', 'short_name': 'US'}, {'types': ['postal_code'], 'long_name': '02169', 'short_name': '02169'}], 'geometry': {'location_type': 'APPROXIMATE', 'location': {'lng': -71.00379099999999, 'lat': 42.252297}, 'viewport': {'southwest': {'lng': -71.00513998029149, 'lat': 42.2509480197085}, 'northeast': {'lng': -71.00244201970848, 'lat': 42.25364598029149}}}}]} {'status': 'OK', 'results': [{'formatted_address': 'Acadia National Park, Mt Desert, ME 04660, USA', 'types': ['establishment', 'park', 'point_of_interest'], 'place_id': 'ChIJJSmiDrKjrkwRhFVV_A4i32I', 'address_components': [{'types': ['establishment', 'point_of_interest'], 'long_name': 'Acadia National Park', 'short_name': 'Acadia National Park'}, {'types': ['locality', 'political'], 'long_name': 'Mount Desert', 'short_name': 'Mt Desert'}, {'types': ['administrative_area_level_2', 'political'], 'long_name': 'Hancock County', 'short_name': 'Hancock County'}, {'types': ['administrative_area_level_1', 'political'], 'long_name': 'Maine', 'short_name': 'ME'}, {'types': ['country', 'political'], 'long_name': 'United States', 'short_name': 'US'}, {'types': ['postal_code'], 'long_name': '04660', 'short_name': '04660'}], 'geometry': {'location_type': 'APPROXIMATE', 'location': {'lng': -68.2733346, 'lat': 44.3385559}, 'viewport': {'southwest': {'lng': -68.4344785, 'lat': 44.2350589}, 'northeast': {'lng': -68.1591412, 'lat': 44.40370240000001}}}}]} {'status': 'OK', 'results': [{'formatted_address': 'Adams National Historical Park, 1250 Hancock St, Quincy, MA 02169, USA', 'types': ['establishment', 'museum', 'park', 'point_of_interest'], 'place_id': 'ChIJbbPB5rB844kR7hOzzjBr4Cs', 'address_components': [{'types': ['establishment', 'point_of_interest'], 'long_name': 'Adams National Historical Park', 'short_name': 'Adams National Historical Park'}, {'types': ['street_number'], 'long_name': '1250', 'short_name': '1250'}, {'types': ['route'], 'long_name': 'Hancock Street', 'short_name': 'Hancock St'}, {'types': ['locality', 'political'], 'long_name': 'Quincy', 'short_name': 'Quincy'}, {'types': ['administrative_area_level_2', 'political'], 'long_name': 'Norfolk County', 'short_name': 'Norfolk County'}, {'types': ['administrative_area_level_1', 'political'], 'long_name': 'Massachusetts', 'short_name': 'MA'}, {'types': ['country', 'political'], 'long_name': 'United States', 'short_name': 'US'}, {'types': ['postal_code'], 'long_name': '02169', 'short_name': '02169'}], 'geometry': {'location_type': 'APPROXIMATE', 'location': {'lng': -71.00379099999999, 'lat': 42.252297}, 'viewport': {'southwest': {'lng': -71.00513998029149, 'lat': 42.2509480197085}, 'northeast': {'lng': -71.00244201970848, 'lat': 42.25364598029149}}}}]}

使用結構正確的json,您可以執行以下操作:

import json
import pandas

df = pandas.DataFrame(json.load(open('example.json', 'r')).items())

頂級json屬性名稱將在第0列中,而相應的值將在第1列中。這也適用於嵌套在原始對象中的任何json對象。 我無法將其與您的json樣本一起使用,但可以在此處與第一個示例json一起使用: http : //jsonapi.org/examples/
