Simple pandas dataframe question

[popohoma]

Hi all,

I am new to pandas and have a real simple question for all of you but it will make my day to day presentation more intuitive.

I am trying to merge few common key value into one (please see below picture).


This is similar to excel function "Merge and Centre" where values in different cells can be combined into 1 single cell/value. I know how to do it while concating multiple dataframes but in my case it is a single one.

Do you have any clues?

Thanks,

Allen
