Pandas根据另一列筛选列

import pandas as pd

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

# 根据Gender列筛选出Gender为Male的行
filtered_df = df[df['Gender'] == 'Male']

print(filtered_df)

     Name  Age Gender
1     Bob   30   Male
2  Charlie   35   Male
3    David   40   Male
