如何在条件语句中使用str.contains()将函数应用于数据框列的某些元素？

import pandas as pd
import numpy as np

data = {'Name': ['John', 'Bob', 'Alice', 'Charlie'],
        'Age': [25, 30, 20, 35],
        'City': ['New York', 'Paris', 'London', 'Tokyo']}
df = pd.DataFrame(data)

# 使用str.contains()函数筛选包含特定字符串的行
selected_rows = df[df['City'].str.contains('New')]

print(selected_rows)

import pandas as pd
import numpy as np

data = {'Name': ['John', 'Bob', 'Alice', 'Charlie'],
        'Age': [25, 30, 20, 35],
        'City': ['New York', 'Paris', 'London', 'Tokyo']}
df = pd.DataFrame(data)

selected_rows = df[df['City'].str.contains('New')]
print(selected_rows)
