How to sort a dataFrame in python pandas by two or more columns?

Question

Suppose I have a dataframe with columns a, b and c, I want to sort the dataframe by column b in ascending order, and by c

Answer 1

As of pandas 0.17.0, DataFrame.sort() is deprecated, and set to be removed in a future version of pandas. The way to sort a dataframe by its values is now is DataFrame.sort_values

As such, the answer to your question would now be

df.sort_values(['b', 'c'], ascending=[True, False], inplace=True)
