Pandas过滤:返回True/False与实际值

import pandas as pd

# 创建一个示例DataFrame
data = {'Name': ['Alice', 'Bob', 'Charlie', 'David'],
        'Age': [25, 30, 35, 40],
        'Gender': ['Female', 'Male', 'Male', 'Male']}
df = pd.DataFrame(data)

# 过滤年龄大于30的行
filtered_df = df[df['Age'] > 30]

# 过滤性别为男性的行，并只保留姓名和性别两列
filtered_df = df[df['Gender'] == 'Male'][['Name', 'Gender']]

# 过滤姓名为Alice或David的行
filtered_df = df[df['Name'].isin(['Alice', 'David'])]

# 过滤姓名以C开头的行，并返回姓名和年龄两列
filtered_df = df[df['Name'].str.startswith('C')][['Name', 'Age']]
