    I tried to generate a new column by adding two other columns.

    hh_rfm['eRFM']=hh_rfm['MF']+hh_rfm['R']

    This way usually works, however it doesn’t work sometimes.

    I found out the reason being is the type of hh_rfm[‘MF’] is numpy.int64

    and hh_rfm[‘R’] is int

    Is there any easy way to add these two different type columns together instead of using extra function to add two columns?

    Thanks,

    A better way is to convert all the R/F/M index to character strings, then concatenate them together. Use a character RFM index rather than numeric.
