转换数据帧中的嵌套字典？

import pandas as pd

# 创建包含嵌套字典的数据帧
data = {'Name': ['John', 'Alice'],
        'Info': [{'Age': 25, 'City': 'New York'}, {'Age': 30, 'City': 'San Francisco'}]}
df = pd.DataFrame(data)

# 展平嵌套字典
df_normalized = pd.json_normalize(df['Info'])

# 合并展平后的数据帧与原始数据帧
df_merged = pd.concat([df.drop('Info', axis=1), df_normalized], axis=1)

# 打印结果
print(df_merged)

    Name  Age           City
0   John   25       New York
1  Alice   30  San Francisco
