如何根据多个条件将值保存到select pandas行中

import pandas as pd

# 创建一个示例DataFrame
data = {'Name': ['Tom', 'Nick', 'John', 'Amy'],
        'Age': [20, 25, 30, 35],
        'City': ['New York', 'Paris', 'London', 'Tokyo']}
df = pd.DataFrame(data)

# 设置条件
condition1 = df['Age'] > 25
condition2 = df['City'] == 'London'

# 使用loc方法根据条件选择行，并将值保存到新的行中
df.loc[condition1 & condition2, 'NewColumn'] = 'Selected'

# 打印结果
print(df)

   Name  Age      City NewColumn
0   Tom   20  New York       NaN
1  Nick   25     Paris       NaN
2  John   30    London  Selected
3   Amy   35     Tokyo       NaN
