【问题描述】：

您好，我正在尝试清理数据，但无法将 json 文件作为单独的数据框列读取。我在一个文件中有数千条这样的记录：

{"hotel_class": 4.0, 
"region_id": 60763,
"url": "http://www.tripadvisor.com/Hotel_Review-g60763-d113317-Reviews Casablanca_Hotel_Times_Square-New_York_City_New_York.html", 
"phone": "", 
"details": null,
"address": {"region": "NY", "street-address": "147 West 43rd Street", "postal-code": "10036", "locality": "New York City"},
"type": "hotel",
"id": 113317,
"name": "Casablanca Hotel Times Square"}

我尝试将其加载为：

with open('offering.txt') as datafile:
  data_json = json.load(datafile)

但它给出了一个错误，即

JSONDecodeError: Extra data: line 2 column 1 (char 398)

所以我试着这样做

df=pd.read_json('offering.txt',lines=True)

但如果我这样做，我的地址列有嵌套值，我想将它们分隔在不同的列中。怎么办？

df['address']

0       {'region': 'NY', 'street-address': '147 West 4...
1       {'region': 'CA', 'street-address': '300 S Dohe...
2       {'region': 'NY', 'street-address': '790 Eighth...
3       {'region': 'NY', 'street-address': '152 West 5...
4       {'region': 'NY', 'street-address': '130 West 4...

Name: address, Length: 4333, dtype: object

【解决方案1】：

试试：

df = pd.read_json("offering.txt", lines=True)

df_out = pd.concat([df, df.pop("address").apply(pd.Series)], axis=1)
print(df_out)

打印：

   hotel_class  region_id                                                                                                                       url phone  details   type      id                           name region        street-address postal-code       locality
