Description
c = pd.DataFrame({ 'a':[1,2] ,'b':[3,4]})
d = c.iloc[0] # makes a series
e = d.drop(columns=['a'])
'''
a 1
b 3
Name: 0, dtype: int64
'''Problem description
Drop silently fails on series. It does nothing when the user tries an impossible operation (dropping column from a series).
Expected Output
Error should be raised.
'Cannot drop columns from a series'
