giving a name to a pandas dataframe?

Question

When I look to a pd df :

I tell myself I would like to fill the upper left empty space by a dataframe name. Is that possible ?

(Here it would be to put a text on the empty cell on top of "Lib_ze" and on left of "nunique".)

Answer 1

It is possible if set columns names:

df.columns.name = 'text'

Or rename_axis (new in pandas 0.18.0):

df = df.rename_axis('text', axis=1)

Sample:

df = df.rename_axis('text', axis=1)
print (df)
text              nunique
Lib_ze                295
cd_cmn              31870
cd_ze                 295
code_commune_zdc    31870
unite                 638

If set index name:

#df.index.name = 'text'
df = df.rename_axis('text')
print (df)
                  nunique
text                     
Lib_ze                295
cd_cmn              31870
cd_ze                 295
code_commune_zdc    31870
unite                 638
