如何将嵌套列添加到DataFrame

import pandas as pd
from pandas.io.json import json_normalize

data = {
    'name': 'John',
    'age': 30,
    'address': {
        'street': '123 Main St',
        'city': 'New York',
        'state': 'NY'
    }
}

df = pd.json_normalize(data)

print(df)

  name  age address.street address.city address.state
0  John   30    123 Main St     New York            NY

data = [
    {
        'name': 'John',
        'age': 30,
        'address': {
            'street': '123 Main St',
            'city': 'New York',
            'state': 'NY'
        }
    },
    {
        'name': 'Jane',
        'age': 25,
        'address': {
            'street': '456 Elm St',
            'city': 'Los Angeles',
            'state': 'CA'
        }
    }
]

df = pd.json_normalize(data, record_path='address')
