Pandas: how to sort dataframe by column AND by index

Question

Given the DataFrame:

import pandas as pd
df = pd.DataFrame([6, 4, 2, 4, 5], index=[2, 6, 3, 4, 5], columns=[\'A\'])

Results in:

<         


        

Answer 1

The other answers are great. I'll throw in one other option, which is to provide a name for the index first using rename_axis and then reference it in sort_values. I have not tested the performance but expect the accepted answer to still be faster.

df.rename_axis('idx').sort_values(by=['A', 'idx'])

     A
idx   
3    2
4    4
6    4
5    5
2    6

You can clear the index name afterward if you want with df.index.name = None.
