使用依赖于条件语句的不同函数创建多个新列

import pandas as pd

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

# 使用条件语句创建新列
df['Age_Category'] = df['Age'].apply(lambda x: 'Young' if x < 30 else 'Old')
df['Gender_Category'] = df['Gender'].apply(lambda x: 'Male' if x == 'Male' else 'Female')

# 打印结果
print(df)

      Name  Age  Gender Age_Category Gender_Category
0    Alice   25  Female        Young          Female
1      Bob   30    Male          Old            Male
2  Charlie   35    Male          Old            Male
3    David   40    Male          Old            Male
