How to concatenate the values of a column based on some columns in Pandas?

Question

Let's say I have the following dataframe:

id	id_2	id_3	text	integers
0	1	2	lorem	integers1
0	1	2	epsilon	integers2
0	1	2	text3	integers3
0	1	3	text4	integers4

My question is:

1. How can we merge text columns given the condition id, id_2 and id_3 are the same. I mean, I want to extract the values from 'text' column separated by comma or space and respecting the condition that id=0,id_2=1 and id_3=2 Output wanted: 0 | 1 | 2 | lorem epsilon text3 | sum(integers1,integers2, integers3)

Thanks
