Pandas - remove the label of the column index

Question

I have a dataframe as follows:

PLEASE_REMOVE  2013  2014  2015
 THIS_IS_EASY
-------------------------------
          Bob     0     3     4
         Mary     2          


        

Answer 1

In Pandas 1.0.3 the following works:

df.columns.name = None

The 'accepted answer' above, del df.columns.name, leads to: 'AttributeError: can't delete attribute'
