How to sort values by a column in a pivot table

Could you please help me with sorting the values by a column in a pivot table in Python?

Please, help me to sort my pivot table by a date column where ascending=False.

>Solution :

Remove [] from index, columns, values for remove MultiIndex and then sorting columns by DataFrame.sort_index:

            .sort_index(axis=1, ascending=False))
