如何在pandas中排列数据集？

import pandas as pd

# 创建一个示例数据集
data = {'Name': ['Tom', 'Nick', 'John', 'Amy'],
        'Age': [25, 30, 18, 22],
        'Salary': [5000, 8000, 4000, 6000]}

df = pd.DataFrame(data)

# 按照某一列进行升序排序
df_sorted = df.sort_values('Age')

print(df_sorted)

   Name  Age  Salary
2  John   18    4000
3   Amy   22    6000
0   Tom   25    5000
1  Nick   30    8000

df_sorted = df.sort_values(['Age', 'Salary'])

print(df_sorted)

   Name  Age  Salary
2  John   18    4000
3   Amy   22    6000
0   Tom   25    5000
1  Nick   30    8000

df_sorted = df.sort_values('Age', ascending=False)

print(df_sorted)

   Name  Age  Salary
1  Nick   30    8000
0   Tom   25    5000
3   Amy   22    6000
2  John   18    4000
