如何基于条件在Pandas DataFrame单元格的字典中创建新的键值对

import pandas as pd

# 创建示例DataFrame
data = {'Name': ['John', 'Emma', 'Mike', 'Sophia'],
        'Age': [25, 28, 30, 27],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

# 根据条件在DataFrame单元格的字典中创建新的键值对
df.loc[df['Age'] > 26, 'Additional Info'] = {'Key': 'Value'}

# 打印结果
print(df)

    Name  Age      City Additional Info
0   John   25  New York             NaN
1   Emma   28    London   {'Key': 'Value'}
2   Mike   30     Paris   {'Key': 'Value'}
3  Sophia   27     Tokyo   {'Key': 'Value'}
